@Contractor. I said "reduce" not "get rid of." I'm saying we should reduce car use by people who don't need to use them.
The majority of cars on the road today are carrying one person, who has nothing heavy to carry. Of course we need roads for commercial vehicles and taxis. It's the ridiculous amount of people using cars just to get around that are the source of most congestion.
If our roads were reserved for commercial traffic and taxis only, we wouldn't need 4 lane highways running right through urban areas, with attendant pollution, noise levels, splintering of neighborhoods, and other reductions in livability. I'm fine with you thinking I'm an idiot, I just don't want you to think I'm an idiot because you didn't read my post carefully :)
oh. hi! i guess i walked in to the wrong room.
Well, the cheapest and most future-oriented solution would be to reduce cars by NOT improving/building out roads and encouraging people to use public transportation and bicycles. Don't you think?
