I for one am quite happy that Mercedes is committed to a physical button for hazard lights, parking assist overrides, and the other controls that are used so very...rarely. Perhaps they'll do something about the less commonly used buttons like climate control for the next model redesigns in five to seven years.
I really struggle to understand what's so damned difficult about this. They've admitted touchscreens annoy the hell out of drivers and capacitive touch buttons are even worse. Is it really going to take yet another lifecycle before they actually do something about it?
My guess is that people impulse buy things that look sleek and shiny then suffer through the consequences
