Some proposed design principles:

1. It's a car.
2. It's not a goddamn TV.
3. It's not your goddamn ads platform or subscription service.
4. It is, however, a piece of life-safety-critical equipment.
5. Because it's a car, the driver wants to deal with car stuff like driving, navigating, fuel, roads, obstacles, and not killing people.
6. They also want to make it passably comfortable by messing with the heat or AC, the fans, the windows, and the fucking moon roof.
7. Messing with your phone while driving is Actually Illegal these days in civilized parts of the planet. This is for good reason: people get killed that way.
8. If the car requires messing with your phone, or messing with something that is basically your phone, then you have failed.
9. There should be a big knob with a fan icon on it. Turning this knob all the way to the left causes the fan to turn off all the way. Turning the knob all the way to the right causes the fan to turn on all the way.
10. If I ever have to use a touchscreen to control the side mirrors, I will become an extremely unhappy ape.
