Right now we don't know if electric cars that Tesla has will be the formula for everybody else or that it will be the standard (optimists will claim so). There are so many problems we are ignoring and the biggest which ansible brought up is the battery & cost. Could you charge your battery faster you can fill up your tank with fuel? Yes I'm sure it's improving every year but there's going to be a lot of time that will be required. There are so many other economic unknowns during this time. What if gas became so abundant and cheap due to continued oversupply from some determined group of oil producing countries hell bent on making sure there's a market for their black gold? What if we improved and lowered the cost of extracting oil deep deep below the earth and run into an ocean size worth of supply? What if car technology improves suddenly that burning fuel becomes extremely efficient that batteries can't match? What if somebody comes up with a new type of fuel concoction that you could put into any old used car and get crazy mileage? If we do arrive at a point where everybody is producing electric cars, wouldn't there still be an interest in buying out existing gas stations and turn them into super charging stations where you can just drive your car through a tunnel and come out the other end with batteries fully charged? Or would battery become so crazy good that you charge it overnight and it lasts for deacades (you gonna put a mini nuclear reactor in your car?)? Maybe it will be possible to just subscribe to some power station in the orbit that charges your battery constantly wirelessly. I'd love to see that happen but the time it will take to get all of these things right is quite long and a lot of things can change during that time. I hope you are right, I really look forward to that day when we can say the hell with relying on oppressing people (creating some very angry people that are willing to blow themselves up to make a point) in countries where their leaders get all of our dollars in exchange for that sweet sweet black gold.
