the issue here is, people like there cars, people want there own car, beacuse they like cars, i want my own car to have, it gives me a feeling of being able to do things myself at my own convenience without having to get into a bus full of people i don't know at there own time tables. i can leave my house and get to wherever i want to go when i want with whome i want. a large majority of the pollution created is not from the automobile, its from factories, and power plants, cutting pollution form automobiles is just a small portion of the picture, a lot of the factories and power plants going like in china have no emmition control, which allow them to pump as much smog in the air as they please.

in addition, you remove private transportation from the equation, and i don't think thats a good idea in itself compleetly, what about people who got a education or are getting a education like myself fixing private owned cars. if the number of private owned cars go down, people lose jobs, those trying to get one find it harder to do so, the dealerships trying to sell those cars find it harder, the factories making those cars for the dealerships have less cars to make, which leaves out more jobs, then the people making the parts for the cars find less jobs too... and i bet bottom dollar if the jobs start going down, there going to start cutting down jobs here in favor for cheaper labor in china and Mexico.
