Because FSD driving not navigation is going to be held (rightly) to a much higher standard than human driving.

Humans are fallible and we have other sensors, like hearing, or touch (through feedback on the steering wheel) that are also involved in driving.

We already have other sensors that are not vision that work with us when driving like ABS and electronic stability.

The other reason it's dumb is that adding LIDAR and proper sensor fusion makes things better and the cost of LIDAR is rapidly dropping as its installed across new fleets in CN and elsewhere.
