They are nice cars that burn fossil fuels somewhere else, preferably places where rich people and SV types do not live. As their PR spin after the recent "autopilot" fatality shows, they are just another car company with much better marketing.
We hardly burn any fossil fuels for electricity where I'm from (Toronto). And even if we did, it's more efficient to burn them at industrial scale than in individual cars.
I never said they were less efficient, but they do pollute. As to the ones that do not use fossil fuels, they are few and far between at the moment. The bulk of our electicity production is still gas a coal. Toronto may get a lot of green electricity from Quebec hydro, but please do not claim that this is anything but an outlier at the moment.
Electric cars are more efficient than ICE vehicles and they pollute less, but they are not powered by rainbows and dreams of utopia. Zero emmisions at the tailpipe is nice, but don't try to make the claim that these cars are not following that grand SV tradition of moving the negative externalities somewhere else so that someone else can pay the cost.
