>It might help reduce emissions directly in city centers, but the power plants are generally not that far from large cities anyway. Since EVs are also much heavier in general (Tesla P85D is ~4936lb vs a Corvette at ~3347lb or a Civic at ~2738lb), even though they are pretty efficient, they're still pretty close (when I ran the numbers before, they were higher) in greenhouse gas emissions once you factor in how much energy it takes to drive one vs an ICE vehicle. Bigger issue with weight is the road wear and tear it causes. The effect isn't even just linear, but much more than that – some studies have calculated that road wear increases to the fourth power in increased vehicle mass[1]. By that account a 5000 lb. Model S causes 16 times the road wear compared to a 2500 lb. compact car. Also, cars do not “eat” the road, they pollute the local air with it (especially the smaller particulates are very nasty stuff indeed in heavily trafficked areas).
