The car wars.

Carsharing Vs Taxi, Vs Private car Vs Ridesharing or Carpooling.

Which will be the cars of the future?


We are living in a war, where the property and the more or less efficient use of the vehicles we use to move around the city is at stake.

There is a struggle of cross-interests between users in need of transport, and different service providers (such as public transport, or rental of vehicles with or without a driver), or suppliers of mobility-related products (like cars, insurance or fuel sellers).


Regarding this war, these days we can see on TV a car advertisement, where some young people buy a new one, but they leave it parked to go downtown by bus.

That‘s a car manufacturer sending its customers the message: “Buy me a car that you can’t use.”

It is shocking at a time when:

  • Young people are getting their driving license older, and many prefer to get a good mobile phone or computer instead of a car. Because millennial already know that it is not necessary to physically own the car (which carries some complications they don’t want), but they only need access to a way to move from one place to another, in a timely, easy and economical way.
    However, the announcement seems to try to reverse this trend, showing us two young people happy to have a new car.
  • We live in the age of “carphobia”. The urban authorities, the press and the progressive people agree to blame the car for all the evils, and to tell us that we must restrict traffic and parking in the city center.
    However, the announcement seems to try to decouple the ownership and use of the car. To have a car of your own (that’s cool) it’s not the same as to use it daily (which is problematic).


And we can only agree.

If you give yourself a whim, you buy the car of your choice, and you have it stored in the garage, to take a ride to the beach one of those days, there is nothing wrong with it. Same as if you can afford to collect them, and you own several cars! You don’t harm anyone with it.


What creates problems, is not having a car, but too many people having to move theirs every day.


It happens that cities grow nonstop. You can no longer get to work by walking, and it is increasingly difficult to take less than an hour on public transport. More and more people are going by car and it is difficult to park them all in the center, in the industrial estates or in the business centers where the workplaces are.

In addition we are subject to schedules that make most of us to move at the same time, and at peak hour we get traffic jams, which make us lose time each day (three or four times more than normal), and that cause the car to consume too much fuel and to over pollute the air (an 80% more).


Opportunists appear to add fuel to the fire.


New Silicon Valley technology companies, backed by multi-million dollar venture capital investment funds, are planning a good fishing in troubled waters.

They take advantage of the situation to send us their message: “Having your own car is awful. Do not have your own car, rather use one of mine.” Some say: “rent it by hour” and others say “let yourself be carried by one of my drivers, who (since I don’t have them on the payroll and I set the company headquarters in Delaware, where I barely pay taxes) it’s a little less expensive for you than to ride in a regular taxi”

Let no one be fooled:
Carsharing is not the solution.


This may be useful for someone who only has to move sporadically; but most workers can’t afford paying to those companies every day.

Those platforms (which call themselves “carsharing”, although they are pure business and do not have any collaborative economy) are advertised as being very “cool” because they “share a car”, and even predict that in the future there will be no private cars, but only fleets of their rental cars and their taxis; And even that they will all be robotized and will be self driven (this is what they hope, to save paying a salary to the driver).

But the truth is that citizens continue to suffer from the high cost of transport (which is the third largest item of family budgets, after housing and food), and we continue to have traffic, parking and pollution problems in cities.


With all this mess, opinions are divided:
Who is to be blamed? Car or driver?


If we know that driving your own car is five times more expensive than on public transport, and it congests and pollutes more the city, Why do we keep doing it?
Because for many, going by public transport (which is a more economical and sustainable solution) would mean losing each day more than an hour outward and another one to return.
Faced with this situation, when it takes half the time by car, many of us feel that “we have no choice but to go by car”. And that’s when we become slaves to use the car every day to go to work, or to study.
And the worst thing is that each one goes driving his own car.

Instead of seeking to apportion blame, it will be better to study the case in depth, to find wiser and more creative solutions (something better than going for the easy: banning the car and fine the driver, or doing science fiction with self driving or flying cars).

The data from Madrid are overwhelming, and give us good clues:

  • 83% of the vehicles that circulate are private cars.
  • Of every five cars, four carry the driver alone.

Every day more than four million free seats are being wasted in Madrid (this is more seats than people traveling by metro and bus together), and most of them go almost empty during rush hour, just when more transportation problems there are.

This is very inefficient. And, every time assets are wasted, someone bears the brunt of it. Unfortunately, it is usually the weakest.


Here is a clear opportunity for improvement.

It does not make sense that, precisely when there are not enough means to transport people, is when more vacancies are wasted in cars.

And besides, anyone who has looked around while stuck in a jam on the radial or ring roads, knows that there are thousands of people going in the same direction, one behind the other, but each in his own car.

Pollution rides in the empty seat Com

The best solution is ridesharing or carpooling.

Why can’t several people go to work together in each car, in the style of what BlablaCar does on interurban trips?
In addition to saving costs, we would remove cars from traffic and would greatly alleviate problems in the city (traffic jams, pollution, parking), which we end up suffering ourselves.

If we take care of what is in the interest of society and citizens, the key to solving our problems is not to share the cars (the “carsharing”), but to share the trips (the “ridesharing” or “carpooling” ).

With the carsharing platforms, it’s doesn’t matter if first you get a “taxi” and then I take it, or if you rent a car first and then I rent it. Each car keeps carrying only one traveler, and it doesn’t solve any problem.

The wonders of “car sharing” that those platforms want to sell, are not such a solution, because they do not actually remove cars from traffic.
In fact, the opposite is true today:
Manufacturers are delighted with the sales to equip these new fleets of more cars that are put into circulation (like Daimler with the Car2Go).

However, there will never be enough taxis or rental cars to take us all at rush hour. For one simple reason: because if there were, they would be idle for the rest of the day, and these companies do not invest or get into business to lose money.


The wise thing is not to put in circulation new cars, but to use well those cars we already have.

Instead of running more taxis, or new fleets of rental cars, let us take advantage of the huge number of free seats that our private cars carry, for the benefit of the citizens themselves!

To improve quality of life, taking advantage of sharing car trips, you only need a smartphone app that points you to other people willing to share expenses and following a route similar to yours.

Collaborating, we will achieve it.

Join DedoCar, the community of urban hitchhikers who use a carpooling app to save and avoid problems!

The DedoCar app will tell you on the go with who you can share your journey by car to go to work, to study, to return home, or any other route in the city.

You choose what is most convenient to you.

You can go as a passenger who enjoys the comfort and speed of a car with a driver, at a bus price; Or (if you like to drive your own car) you can be the driver who shares your free seats and recovers up to three quarters of your expenses.

The more people we go together in each car, the more we save, and the better quality of life for everyone we get.


The most effective way to avoid pollution caused by cars

On behalf of the City of Madrid, Siemens has done an analysis of the causes of pollution in the city.

We agree that many locals are throwing money, burning fuel, clogging the city and polluting the air much more than necessary; Because each one is driving his own car, and on most of our trips we squander four of the five seats in the car.


Now it’s time to find the best solution

Would you like to go to work with the comfort and speed of a car with a driver, but at a bus price and polluting much less?

Now you can, thanks to a carpooling app that helps several people going in the same direction to go to work sharing a single car, and to move around the city in a more efficient, economical and sustainable way.


With the urban hitch-hiking app DedoCar,

we will use fewer cars, because we will take advantage of their free seats to carry several people on each trip. By dividing expenses equally between the driver and several passengers, we all save a little each day. It is even better than BlablaCar, because it serves to move you every day around the city, and solve several of your problems.

By sharing car trips, we all gain in quality of life (fewer cars, fewer rush hour traffic jams and fewer parking problems) and we reduce pollution without having to invest in more subsidized means of transport or in deterrent park and ride. And there is no rush to remove our current cars and buy new ones, since anyone carrying 3 passengers, immediately multiplies their efficiency, consumes less energy and pollutes a quarter.


There will no longer be any pollution peaks, so it will not be necessary for the City Council to impose unpopular measures or crude solutions, such as putting tolls on Madrid residents, or bann them from driving or parking in city center.


But it seems that we are crying in the wilderness.
How do we explain it, for the authorities to help us?


In the end, we will have to do it the citizens ourselves.

Why Google and Amazon are aiming in the wrong direction?

Society asks big enterprises to solve people’s real problems, and most of them are transport related. A more human centred way of innovation is possible, with a carpooling app.

The development of society has much to thank to Google searches and also to the long tail distribution of Amazon.
But, being sensible and realistic, they miss the shot when they depart from what they know well, and try to innovate inventing toys for big children.


Amazon drone

Amazon and the postmen drone:

Nowadays technology allows sending small loads in a flying device programmed for it. But it doesn’t mean that it won’t find another type of problems. Amazon thinks that the airspace above our heads is free and at their complete disposal, and that they can send flying gadgets to everywhere they want and whenever they want. But aeronautical regulations and air safety exist!
Will there be aerial maps so detailed that they show the trees, the poles and the cables, so GPS guided drones don’t clash with them?
Considering that, when a messenger brings an order to you, it’s usually hard for him to find you home on the first try; Then, to be reached by drone, will you have to leave the window open all day and put a radio frequency beacon on it?

Google self driving car

Google and the self-driving car:

The only meaning of a car is to carry people. And most people like to drive.

When lots of cars carry few people, they cause huge problems (traffic jams, parking problems, air pollution …); If someday cars carry no one, they will cause many more problems that today.
That’s why building a driverless car is a waste of time, if not inefficient and counterproductive.

CarPooling with DedoCar

How to better target the efforts?
A carpooling app.

Instead of trying to get profit by exploiting a hypothetical fleet of postman drones or robo-taxis, it would be far better for mankind that companies like Amazon or Google would foster the greater efficiency of the collaborative economy and devote the intelligence of their brilliant engineers to find a way to make it easier for people to save money, pollute less and stop traffic jams, depletion of natural resources and climate change.

Instead of replacing the “human factor”, they should help us to use better and more efficiently our private cars, as we move through the cities.

Instead of each traveller paying the full expenses of moving his own car (or, even worse, a taxi fare) it is much better that one of the occupants of the car (who doesn’t mind driving) remains his proud owner, and just shares the travel expenses with some other neighbours and companions, carrying them in his car’s empty seats, while on their way to the workplace or back home.

That’s what BlablaCar successfully does (for intercity travels), and what DedoCar app intends to do for our daily commutes too.

Carsharing vs. ridesharing benefits

Discover why ridesharing is much better for commuters and citizens than carsharing.

Our original post and infography “Who’s who of Carsharing” was published as a colaboration at Daimler’s Move Forward blog. To read it, please follow this link:
Carsharing vs. Ridesharing: Which New Technologies Solve Commuter and City Problems?



To really solve city transport issues, we propose to improve the Blablacar ridesharing model, with a real time urban auto-stop app.

In DedoCar we are creating a huge community of commuters that use an urban auto-stop app, which helps them to move by the city in a cheaper and more efficient and sustainable ridesharing way. See for more info about how ir works.

Matching in real time the drivers and passengers with compatible paths, allows us to improve the BlablaCar’s model, to make it suitable for millions of daily rides by the city, with an automatic and fair sharing of travel costs between all car occupants (the car’s driver doesn’t make any money, but recovers up to 75% of travel expenses), and arranging the ridesharing on the fly, thus removing the burden for travellers to publish and negotiate their trips some days in advance.

Pretty soon, it will be possible to move around the city at nearly the speed and comfort of a car with driver, but at bus cost.

¡Let’s join the DedoCar Community!

How many empty car seats should we harness through ridesahring, to end up traffic jams and air pollution?

We have a problem in the city: traffic jams cause 80% additional pollution and increase travel times three to four times. This happens because too many cars that carry nothing but the driver and several empty seats, collapse the traffic routes. If we share some of these empty seats (carrying people who go in our direction) we can easily get rid of these problems.

We currently use our cars quite inefficiently. The vast majority of them carry only one person (the driver), and waste four empty seats. We can say that, every five cars that circulate by a city as Madrid, four of them carry just the driver, and the fifth one carries only two people.

Thus, we use many more cars than necessary, squander an increasingly scarce fuel and we are polluting excessively the air we breathe. It is not really the smartest way to get around, because we are throwing away money and creating health, traffic and parking problems for ourselves.

Everything gets complicated by the daily evolution of traffic.

We citizens are subject to certain schedules and the demand for transportation seats varies greatly throughout the day. There are two very marked demand peaks, at the morning and afternoon peak times, when going and returning to work, as can be seen in the green line of the graph.

However, the maximum number of vehicles admitted by streets and roads is constant (blue line of the graph), and something similar happens to the number of seats available on public transport.


Unable to handle these peaks of demand, the usual traffic jams happen at rush hour, when the available transport means doesn’t seem to be sufficient.

However, this is not entirely true.

As a million cars circulate in Madrid every day, it means that we are wasting four million valuable empty seats (there are more empty seats that people travelling by metro and bus). And besides, most of these seats are vacant at peak times, just when they are needed most and when we suffer most transportation problems.

Could we take advantage of our empty seats to have fewer problems and live better?

Lets study in detail why traffic jams occur, and their pernicious effects:

In the following graph, the black line represents how the number of vehicles that circulates over time (the actual traffic) evolves. On the left side we have a growing but fluid traffic, which is able to satisfy the demand, because the cars can travel without problems. Problems start when the maximum capacity of the road is reached. This usually happens in Madrid’s M-30 about 7:00 in the morning.

When the number of vehicles entering the roadway exceeds its maximum capacity, it becomes saturated. The cars start braking and, suddenly, the capacity of the road to admit vehicles is drastically reduced.


From that moment on, despite the fact that demand continues to rise, the number of cars circulating actually drops. We pass into a congested traffic situation, where the black line showing the real traffic decreases and drifts apart from the demand curve (the discontinuous blue line, which continues to grow); So that more and more of the demand is dissatisfied. Cars have to wait to be able to enter the main routes, or they have to take a detour looking for an alternative road.

The most notable and damaging effects of traffic jams are:

  •  A sharp decrease in speed (eg. in Madrid’s M-30 the speed drops from 55 to 15 MPH), which makes travel times three to four times longer.


  • Each car caught in the jam pollutes an 80% more (According to a study of M .Treiber from the University of Dresden)


Once we have a congested traffic, the situation seems insurmountable, since there is too much difference between the number of cars that want to circulate and those who really get it.

The only solution is to anticipate, removing from the traffic a sufficient number of vehicles as to avoid that the roads become saturated.

For this purpose, we can take advantage of the empty seats in our cars.

Imagine that we managed to convince a certain number of people to offer the empty seats in their cars to carry some passengers, while they are on their way to their daily occupations. Therefore, each of them will remove from the traffic several vehicles (from one to four, according to the number of passengers they carry), since each of those now going as passengers, no longer need to move their own car.

This behaviour change, which efficiently takes advantage of the sharing of the empty seats of some cars (instead of going in each one’s own car), causes two benefits in traffic:

  • All the people who need it can be easily carried, in a smaller number of vehicles (without getting to saturate the road).


  • Compared with the situation we had when the traffic was congested, the effective capacity of the streets to transport people increases (according to the green area of the following graph)


It also has two effects on pollution improvement:

  • First of all, the passengers’s cars no longer pollute, since they remain parked.
  • In addition, by removing these cars from traffic, routes do not become saturated, and we prevent traffic jams.
    This practically doubles the effectiveness of the fight against pollution; Because all cars are in a fluid traffic, and will no longer pollute that additional 80% that they emitted when they were in congested traffic.

How many rides do we have to share to avoid the traffic jam?

To keep a road decongested, we just have to remove the excess cars that cause the jam (the number of cars between the saturation level of the road and the peak of the demand).

To achieve this, it would suffice to share a relatively low number of rides. The fact that each carpool can offer up to four passenger seats, is a multiplier effect that works in our favour.

In the worst case (if each car shares only one passenger, and still keeps three empty seats), it would be necessary to share as many cars as the surplus demand over the capacity of the road.

However, in the best case (when each car completes all its empty seats and carries four passengers) the situation is as shown in the following graph, and it suffices to share a number of cars four times lower.


Although the rest of the vehicles continue going the same as before (only with their driver); both these and the shared cars will enjoy a fluid traffic, with the advantages for everyone of a great reduction in pollution and travel times.

To sum up:

Traffic jams in the city, cause 80% more pollution and three or four times longer travel times. We can easily avoid them, by simply sharing the empty seats of some of our cars, to carry as passengers other people going in our direction.

DedoCar is a smartphone application that finds an empty seat in a car that can carry you; Or if you decide to share the empty seats in your car, it locates on the fly the passengers that you can carry while you are on the way to your destination point.

DedoCar’s vision on urban transport in the immediate future.


Some say the only option to get around the big cities will be fleets of robo-taxis (cabs without a driver). Our vision is more realistic and immediate:

The cars are the same that we already had and they continue to be private, but now they consume and pollute a quarter than before, and no longer cause traffic jams; because instead of each people driving its own car, an urban hitchhiking system (smartphone aided) has been reinvented. Municipalities realized that most people goes to work (and back home) by the same time; precisely at the times when there were more empty seats in the millions of cars getting around any big city at rush hour. There were so many path matches, that a coordination system to fill the vacant seats of a car along the route of it’s driver could be easily arranged.

All you need to travel is the app on your smartphone.

Now, just a few really need their own car, because you just get out, tell your smartphone where to go, and the first car going that direction with a free seat, picks you up. This service has been very successful and has spread quickly by all the major cities in the world, thanks to the advantages for its citizens: Is not only true that drivers save 75% of the expenses they had before, and passengers go with the convenience and speed of a taxi, at near bus fare; but also, as fewer cars are riding the street, we finally have stopped air pollution, traffic jams and parking problems.

When cars were used efficiently, problems ended.

Oil reserves will last for several generations more, and can be devoted to produce new synthetic materials (rather than burning in car engines to produce smoke and greenhouse gases). Cities like Beijing, that before had clear skies just a couple of days a year, are again liveable and nobody longer talks about the dangers of climate change.

It is not science fiction. It’s for now!

What would you think if I tell you It’s not a utopian vision, but some of us are already hands on working on it and, if we get enough support, we can achieve it next year?
