Nothing wrong with wanting an electric car- as long as you know going in what the true economics of it are. It will improve air quality in cities, relocating the pollution to the rural areas with the coal/oil/NG plant, with no net benefit (yet) for the planet. (I'm avoiding nuclear on purpose.) In countries and regions where the grid is mostly renewable power, electric cars will be a net gain for the planet. Today in the US, where you do your own charging via PV, it's a net gain for the planet, though not yet for your pocketbook.
Carbon tax on fossil fuels, if done well, could shift the power mix in a direction which would benefit future generations but public trust in governments to do things well and fairly isn't at an all time high and next month's mortgage, insurance, car loan, credit card bill is the focus for most. In the US whatever simplistic media message is repeated the most, wins.
