Car sharing

Car is one of the most comfortable types of vehicles but it is the main disturber of the comfortable urban life: traffic jams, millions of cubic meters of exhaust gases, wheels ribbon, noise, vibration etc. Moreover rate of car number growing breaks all records.
There are two ways to mitigate these problems:
- car enhancement,
- car-use reduction.
The car enhancement is a prerogative of the car producers but the car-use reduction completely depends on car owners. The car numbers is growing in parallel with reduction of average number of car occupants and today it is around 1.6 men per car. Therefore this factor has high potential for optimization. The same is about use of car cargo capacity.
Correspondingly, if you are a car owner and you want to improve the situation, you can share the trip with friends, colleagues or someone else. If you live in the countryside, you can also help delivering some food to your urban colleagues.

I propose to put here links to sites that help sharing cars like liftshare.com, greenautobook.com
I think it also nice to post here reviews, proposals, ideas regarding the topic
