I own an ID.4. The capacitive steering wheel buttons were probably my biggest fear when we bought this car.
But, they work great. In a year (with 23,000 miles) I've only had a miss-touch a couple times. Swiping to change volume is way better than button pounding.
The capacitive temperature and volume controls under the screen work just fine, too. Now they do need to be illuminated, which they will be in the 2024 model, but it's great to swipe to the temp or volume you want.
The capacitive buttons on the dash to the left of the steering wheel work the worst. They are for the fog lights and defroster controls. It just doesn't seem to register where you press, so that takes a couple tries, but they aren't used often.
I'd honestly be sad to see them go.
Maybe he'll accidentally fall out of a window while he's in Russia...
