The problem is not touchscreens. It's the awful implementation. I have a Tesla(never again, ugh) and a Hyundai Ioniq5.
The Tesla has a fantastic touchscreen that integrates well with the car. Also no display behind the wheel. I'm tall, I can't see it.
Hyundai the rear seat warmers are buttons. My passengers are happy. The driver's warmer is buried in a touch screen menu. Which would be fine but the shitty screen takes a minute to boot up which means I can't adjust my seat until I've already driven off and now it's dangerous and fiddly.
In summary: I don't mind if it's touchscreen or not, it has to be fast and reactive.
There's a limit to how many physical buttons before it goes the other way. Hyundai are already at 'enough' and the Kias I've looked at have way too many.
