>> The monodepth space is full of people insisting that their models can produce metric depth with no explanation other than "NN does magic" for why metric depth is possible from generic mono images. If you provide a single arbitrary image, you can't generate depth that is immune from scale error (e.g. produce accurate depth for a both an image of a real car and a scale model of the same car)

I don’t think you need accurate metric depth for self-driving. “seconds to impact” plus a reasonable estimate of one’s speed (one second from impact at 100km/hour is more dangerous than at 1km/hour both because braking distances grow faster than linear and because a hit at lower speed is less damaging) is way more useful than “meters away” for that.
