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.
