Are you kidding? The only feedback that the car gives is the screen, and having it go black for 30 seconds is dangerous and unacceptable for any car, let alone one in this price range. When the screen goes black the driver has no idea of what the car is doing, how fast it is going, if the safety features are working or not... no fuel level, radio, lights, signal indicator, check engine, odometer if the engine is on even. Everything is an assumption at that point as to how the car is supposed to function. I assume Tesla wouldn't put me in a position where I couldn't steer or stop, but how do I know? My screen just went black and the AC is on blast. You seem to have a lot of trust that if this happened once and you still could control the car, the next time it happened it still would do the same thing. What is the basis of that trust?
Any bug in any software package that caused a reboot, from a iPhone game to an enterprise package, would prioritize the patch, and would apologize for the release. This is a serious problem for a company that prides its self on its software.
