For example, here is Audi's A/C controls in all of their new vehicles:

You not only have to take a hand off the steering wheel, but also look to see which lever you want/need to press. If I'm changing the temperature I know where the dial is, but I also have to look to see what I'm setting it to.
I'm surprised people here think analog controls are a bulletproof solution to the same problems you're criticizing Tesla for. I have a hunch that if there were YouTube videos watching people change climate control settings in their car they'd not only be required to take hand off the wheel but also look down and away for a small period of time. Tesla's isn't perfect but you get to keep both hands on the steering wheel and head looking straight, but down ever so slightly.
