My daily driver is a 2003, I had to buy an aftermarket stereo to get Bluetooth. Recently I borrowed a friend's Tesla for a week, and that was a god damned hostile experience. Shift into reverse - from a touchscreen, mind - and suddenly the entire cabin comes alive with beeps and pings, the dashboard changes to 3 different cameras, none of which show me what's happening to the sides of the car. The 3d overview diagram does almost a good enough job, but is that a trash can, a person, or a telephone pole? The computer isn't sure. On top of that, the blind spots are huge and the back window is tiny and heavily tinted, so I have to use the screens to some extent. If I was my car, I'd have turned half that shit off.
