I had a thought the other day... Often the Model S is referenced to the experience of charging your cell phone and having a full charge every day. That got me thinking of the reverse... Imagine if you wanted to check your phone for messages you had to start a little motor and a little puff of exhaust smoke would come out? You would have to keep it running while on a call which would be annoying at best. From time to time your phone would need an oil change or other maintenance so you would have to take it in and get a loaner for the day. Any other analogies?
