The stupidest part of this thing will be the repair costs and corresponding insurance rates. A shopping cart ding can't be repaired with Bondo and paint. Nor can it be repaired by normal paintless dent repair tools because it's 3mm stainless steel. Basically any accident will require panel replacement, since there's only a few shops in the whole country that can repair stainless steel body panels.

A fender repair that would cost $1500 on a normal vehicle will cost $10k. I'm sure we'll see parking lot accidents that total one of these.
