Or have cameras covering the full rear and sides and display them in a
suitable view on the dash or so. :-)

not as effective nor as safe, for reasons already discussed.

good luck trying to determine depth on small 2d display, or being able
to use it at all if the camera has dirt on it or the lens is cracked.

Simple solution.
Then you wash it or get it fixed. If your license says you must wear
glasses and they break, you get new ones, before you drive. .

just about everyone does *not* walk around to check the vehicle for any
damage prior to a trip.

people even drive with the check engine light on, where they *know*
something is wrong, unless the performance has been crippled such that
the car is no longer drivable.

you are also apparently unaware that dirt or damage can happen *while*
driving, at which point, the camera is no longer useful and you have to
turn your head.

or are you advocating that the moment a camera gets dirty, perhaps due
to a passing truck splashing mud or slush, a driver must pull over on
the side of the road and call for a tow?

and then there's still the 2d issue, even if no dirt or damage has
occurred.

turning a head is easy, costs nothing and more effective.
