I think a ban could make sense in very specific areas. I live in salt lake which has horrendous pollution problems. There are many causes for the pollution and we'll have to work through them all, but it wont be solved without pretty much getting rid of gas cars. A ban on selling gas cars specifically in the salt lake valley would show all the residents how serious we are about solving the problem, and people who really want one can still go get one somewhere else.
