>The Tesla's all-touchscreen situation in particular seems like a terrible idea.
Don't knock it until you've tried it. First off, you are completely wrong about it being an all-touchscreen situation. There are plenty of physical controls. Many people like you form conclusions based on not knowing anything about the car other than what you are told by other people. Think for yourself. Take one for a test drive.
And what if I still find that it is terrible implementation by people who should not be allowed to make anything that could be used as a deadly weapon?
It is interesting that Tesla fans can't even imagine for a moment that someone might have actually tried it and did not like it...
In this case, though, this has been basically a solved problem for the past 50 years, if not longer. Yeah, there might be an argument whether a radial switch or a touchpad with gesture recognition is better, and you can play with positioning, but you don't just go to an objectively inferior touchscreen system and then try to make it slightly better.
