Agreed. I mean, it wouldn't be so bad if they used hardware that could keep up with what they were trying to do instead of going as cheap as possible like I assume they do and the program needs time to process every touch.

But even if they were always snappy, volume and climate control should be adjustable with just a glance. It wouldn't surprise me if auto makers think like Microsoft and "optimise" where things are each update, probably driven by someone who has strong opinions on how it should be set up but isn't the one using it because someone else drives for them.
