Why would that be any kind of problem, assuming the 265 is enough for your day, as it would be for almost everybody who wasn't wasting their lives by throwing away hours of their day on commuting?
Last I checked, I routinely have 9 hours of downtime every night. We like to call that "sleeping" where I'm from.
Also, you can charge the car in 30 minutes with one of the (currently free) "Superchargers" that Tesla is installing around the countryside. Is 30 minutes as convenient as the 10 minutes it can take to fuel up and pay for the fuel for a giant American SUV? Nope, it's slightly less convenient, but there are still improvements to be made.
That is very interesting, and I'm sure steam cars are cool.
Also, completely irrelevant if we put the most important factor first - sustainability. If you have to burn as much kerosene to fuel them as you have to burn gasoline to power a normal car, you're still doing just as much eco damage with the steam cars.
The only tech we can entertain for the future starts with the question "Is it clean?" and goes from there. Steam doesn't seem to pass that most basic criterion.
