In a recent video, they were demoing the Aptera which has rear cameras instead of mirrors. They have tiny cameras in little stalks sticking out the sides instead of built in ones like Tesla. The guy demoing the truck was talking about them and he says “We might have to put something shiny on the stalks to comply with regulations”… kind of cracked me up. Seems like you could easily 3d print a 4 inch long stalk and glue a little dental mirror to the end of it to replace the factory mirror. My Father In Law loves printing stuff on his 3d printer.
