Oil won't be going up overnight. There will be a time period over which prices rise. As they rise various users of oil will reduce consumption as alternatives suddenly become cheaper. Hell, look at oil consumption in the US! I can't find the stats right now, but oil demand for personal transportation has been flat or dropping despite the increasing number of cars on the road.

If a gallon of gas ends up at $10 ten years from now, how much do you think people will complain about having to wait an hour to recharge their electric car? Not much I'm guessing.
