The point vs. electrics would be that you always need a second car for longer trips. In my case, I could have an electric car for commuting, and another car for the weekends - or I can have one car, the TDI. Considering all the energy that goes into making a car, I'm pretty sure that having one efficient vehicle comes out ahead.+1
And while the comparisons of pollutants, like NOx and CO2 are made, realize that the higher CO2 from marginally more fuel consumption doesn't materially change what is a high CO2 per mile figure. It is still going to be about half a pound per mile. The growing electric competition pushes closer to .3 lbs per mile (@3mp_kwh, on a 1,000lb/MWh US electric mix).
