They do use touch screen functions --- but mainly for setup and configuration --- not for basic controls while driving.
It's illegal to use a touch screen phone while driving in many areas --- and for good reasons. So why is it ok and legal for manufacturers to mandate the use of their built-in touch screen while driving? Seems contradictory to me.
I love my Ioniq I think a lot of ways it’s a better package than Tesla’s but I still miss the physical buttons from my Honda. I can’t get close to a button and find the right one by feel when it’s a capacitive panel
I regularly drive a fairly new Elantra where all the essential driving controls are still physical with tactile feedback.
My favorite is the environmental control. A single, big easy to find knob to adjust the temperature without your eyes leaving the road. Turn left (counter-clockwise) for colder, right for hotter. The car takes it from there and selects heat or a/c as needed with an appropriate fan speed. You can still adjust manually but I rarely do so.
Emphasis on 'overall package'
