What do you think?

Not yet and who needs a back window with rearview cameras? There exists a metal that will revert to its original form after being dipped or sprayed with hot water. So cars can potentially "repair" themselves to an extent.

Nope. Body shops if anything.

Or pick up girls/gals who had it tough for prom or something ;)

Reminds me of the Walk of shame shuttle service. Check it out :-)
