Tesla is the new Apple, innovating, polarizing, changing the space and forcing others to follow. Apple hasn't done anything since Jobs passed, they just copy everyone else. It's going to be a long time before others catch up to Tesla. Even when the Porsche comes out, there will be no infrastructure to support it, just look at the Bolt, why are people passing on it and waiting for the Tesla Model 3?
I ride in my friends Mercedes, Rolls and BMWs and I agree, they are much nicer inside, but I really don't care. My P100D does everything I need, nobody is keeping up with me around town, it's fun to drive, autopilot is awesome. I never get in the car and think, damn, I need those massaging seats, LED roofs and nice wood trim to make me happy. And I don't miss taking the car in for oil changes, brakes, yearly service. I have enough of that with the exotics. My wife isn't a car person at all, when I ask her why she like the Tesla? #1 answer is, I never have to stop for gas.
