This above website leads to a post that Toyota is planning for a future 
car that has a non polluting engine powered by hydrogen, running on open 
roads free of congestion.

Do innovative technologies like this solve the problems caused by cars? 
and when is the time that the developing countries foster the new 
technologies?

I feel that the innovative technologies are not going to correct the 
problems caused by the cars. Yes, they might address the problem of the 
air pollution but how many new non polluting cars are required to 
replace the old cars? and what will happen to the old cars? will they be 
tipped or recycled?. Even though a country manages to buy the new fuel 
efficient cars, the old inefficient cars usually end up in the third 
world due to financial reasons..still doing their polluting job but at a 
different place.

In my opinion I feel that, the more a city restricts the use of car and 
more it encourages public transit or mass transit the easier the 
environmental and social problems can be addressed.

P.S: It can be found on the link that US is advanced than Japan in the 
field of Fuel Cells  but I wonder how many cars are running on fuel 
cells. If there is a technology that can convert the existing cars to 
fuel cells or hydrogen powered then it would be a better choice than 
buying a new car.
