You have the right idea, stainless steel is supposed to require minimal work, but on a car its much different. You don't typically drive your stainless steel piping and sheet metal at 70-80mph into debris that can result in its surface being ruined over time.

I have a stainless steel fridge and its a fingerprint magnet, I use bar keepers friend on it every week. As far as I can tell from the Cybertruck subreddit, its the only product that works, but thats just for the finger prints.

The most telling sign to me is that you have to do bug removal immediately, no other car requires this.

Anyone who drives highway daily is screwed.
