I hate touchscreens in cars, but I'll give Tesla the fact that their touchscreen is a modern screen that's not a complete piece of crap to interact with.

When phones can run at 30 fps and have no noticeable lag, it's infuriating to switch to a car which stutters on some ugly, unnecessary graphics and takes 0.25 seconds to respond to a touch input. Not to mention the whole "you're supposed to be driving a car" aspect.

You phone doesn't have to survive 125C for ten years of continual vibration.

It doesn't. If you can't provide an adequate user experience free of large input delays, you should have never installed a touchscreen in the first place. Infotainment systems have gotten less bad, but I haven't seen notable advancement in reducing time spent with eyes off of the road the way a physical button or knob does.

They install touchscreens because they think people want them. The cars sell, because the only choice is touchscreens, and their decisions are validated. Rinse and repeat.
