My gas power car sits all winter, I don't start it up one time. Last winter I let it sit for 6 full months, just pop the hood open filled the carb with fuel, pour a bit more gas down the throat of the carb, hook the 12 V battery up and cranked her over, fired up in 5 seconds and ran a 100 miles on the old fuel in the gas tank.....try that with an electric car....one would need to charge it up and who said those electric motors never wear out or rust up, maybe no tune up is ever needed but those motors won't last forever.
Electric cars will be common place when we need them, as long as oil is cheap, those electric cars won't become common place. Only a gas power car could sit for 6 months and drive off with the old fuel in its tank
