Traffic

After driving on a highway I saw how many persons was driving alone in a vehicle. The government wants less cars on the roads, but the amount of people that will need to travel will remain the same. So in what ways can you motivate people to travel together?

It occurred to me then that why do you not force all the people who drive in a car with less than halve the seats of the car not occupied by a person to only use the slow lane with the trucks. While all the vehicle with half or more than half the seating capacity occupied to use the fast lanes.

This will cause more people to buy small cars with only two seats (eg. Smart) and more people will travel to their jobs together.

This in turn will lead to less pollution and we will all save on traveling expenses.

How do you think can we reduce pollution caused by traveling?
