I think they should wait and see. Frankly, by that late date I expect most urban vehicles might be electric anyway for a number of reasons. Screw "carbon," noise and clean air are good enough reasons (not to mention fuel costs).

I think cities could easily incentivize it instead of a ban. Many already have limited access (helps for islands like NYC), so you could have cheaper toll passes for zero emission cars. You could make a large number of tiny car spaces to encourage tiny, urban cars.

While I don;t buy the AGW issue (or more specifically that it is well characterized enough to make predictions on what emissions should be limited to for an accurately predicted effect), I think noise, and lack of fumes is good enough reason. Would even be nice here in ABQ so I can maintain my 100+ mile views out my windows.
