I agree, much of the tech used to make the Teslas has been suppressed for decades. We still have a way to go before the autonomous driving feature is as good as a human driver in all instances but they're making some quick advancements. Our salesperson said it'll be about a year before they get full approval but Elon Musk said the same thing 3-4 years ago and it hasn't happened yet. Time will tell.

They actually have battery coolers/heaters that cycle off/on keep the battery bank in an optimal temperature range now despite weather conditions. If parked outside in extreme cold you'll lose some battery life from this but supposedly there aren't the steep drops in power that people used to experience.

I saw Jay Leno has a turbine car, it looked really interesting!
