You would also run into the problem of certain cars getting banned from congested places simply because of the emissions. But still, I think you could affect a lot. I mean the kind of car I wanted I simply can't buy in Australia because our laws classify it as a 4-wheel motorbike (Renault Twizo or something, can't remember the proper name) and is hence illegal for road use. But electric, single seat, 80km range and 80km top speed is ideal for my commute of some 3km, shopping, etc. I mean I've always had two cars so 'range/performance/no doors anxiety isn't an issue when my second car can be a rarely used sports car...
