Of course it isn't. I don't vote for internal combustion technology at all. Both are environmental problem. Looking at all the (ex) hype about electric cars, sometime it looks like electrics - they clean the environment...
Internal combustion will stay for a long time in heavy machinery, sea and air transport, which is also problem, if not prevalent, so electric cars will bring negligible health improvement to planet. And add all the wars - our efforts to lower carbon footprint on this planet are so funny and naive.
