This isn't likely to happen, but we could learn to just not care. We have bigger problems than worrying about our car's cosmetics. A lot of a car's cost is due to the high cost of perfect finishes. I'd love a car that was cheap to repair, even if it meant leaving some obvious welding showing up on the surface; especially if it was more socially acceptable.
Reminds me of the NHL goalie Gerry Cheevers* who painted stitches on his face mask every time it got damaged by a puck that would have damaged his face instead. Maybe we should celebrate our car's service dings, instead of spending the money to hide them.
My aunt lived in the city. Her car would get dinged all the time.
She made peace with it by putting two crossed bandaids on a ding.
In this other case I have a mark of me being an idiot backing into a telephone pole or another lower car I didn’t see or getting keyed by neighbors.
