The position of the rear camera means that it is exposed to picking up the mud and dirt that normally accumulates in the tailgate area and therefore requires constant cleaning as well as possible wear and tear.
Its shame that SAIC missed a trick there as they could have done the same as VW. My current drive, Golf MK7 SV Match that has similar tailgate opening via the hinged badge has the camera fitted behind the badge. As the camera is fitted near the bottom of the badge cavity , selecting reverse opens the badge just enough to expose the camera but shielding it from the weather. I expect the cost factor decided that one. May be that's an improvement if they go for a mk3...
Slightly off topic, i have, like hundreds of others read all the comments and watched Utube videos so that when we finally receive our cars we can hit the ground running. My one query is the 360 camera and its poor resolution. What do you think or it?. Is it up to scratch, or would you have preferred a a high resolution rear camera and conventional front bumper sensors.
Many thank to all those knowledgeable ones with their comments while we are waiting
