Much like we already mandate things like car lights cannot be on a moving piece of body work in the USA (to ensure lights visible even when boot or trunk open), I wonder if we should ensure that the critical sensors for self driving are hard mounted to the car securely?
There is inevitably going to be occasions this falls off mid-drive - these suction cups are rarely perfect in my experience.
I've always wondered if CarPlay/AndroidAuto one day might somehow just reuse existing sensor suites on vehicles to provide self driving - this would let the cellphone (which increasingly has ML acceleration hardware anyway) still be responsible for the driving with cameras that won't fall off.
