They are underplaying this aspect of saving on the petrol. If we were in 1973 then it would be different, in today's world we are a Trump brain-fart away from a 1973 situation, for instance in Venezuela and what would happen if the Chinese and Russians decided 'we aren't playing any more'? Sure the U.S. is now god-blessed with the fracking miracle but the gas savings is also an option to be independent of the big oil companies. That could be worth more than $$$ to prepper-mentality Americans. The prices didn't even go up that much in 1973 but a lot of queues and rationing went on. The 55 mph speed limit came in. It was not happy times. If Tesla were a bit more frank they would mention this independence aspect, as it is they don't want to scare the children. Nobody knows what petrol prices will be next month so there is no way anyone can put a figure on savings. That said there are plenty of people who have swapped to Tesla and have the electricity bills to prove that the advertised savings are real.
