What does it look like with the M3 display with the durability? Has anyone ever got a mechanical capputt or scratched the surface? What does a replacement cost and how quickly is something like that exchanged in an emergency? The background to my question is how the fact of absolute concentration of operation on this display affects maintenance and longevity. I have experienced smartphones whose displays looked absolutely scratch-free and top after several years at “service users” others in turn got jumps and scratches very quickly. What happens in the event of a complete failure of the display, can you still move the car? The fact that by concentrating on the display no other switches etc. can lock and fail, is quite an advantage to consider.
