Have you ever used iDrive? I've been using it in cars occasionally for at least 10 years and it still confuses me.

I just bought my first vehicle with it yesterday, so maybe I'll get better at it. Touchscreens are not great in cars but if you can perform the action quickly, it beats fiddling with a knob for 15 seconds.

Does it? I can locate and adjust a knob without ever taking my eyes off the road. The same can't be said for a touchscreen.

You didn't answer the iDrive question. I can find and fiddle with the knob/control, but I still need to look at the screen to figure out what actually happened. It's not like a simple volume knob which I can do without looking.

IOW a well-designed touchscreen UI can be better than a poorly designed non-touchscreen UI. And, unfortunately, most car infotainment systems are poorly-designed.
