Yeah. My understanding is that Deloreans were shockingly rust resistant but were also panels specifically so that they could be replaced.
I don't know metallurgy/material science well enough to know if cybertrucks actually used good quality stainless steel or cut corners. And I can easily see a world where people assume the dirt is rust because of paranoia or just looking for internet drama/clout.
But... Rust or no rust, those cars are pretty fucked. Because they don't even have a clearcoat. And considering we are in the season where roads are covered with salt and sand and cars are constantly bombarded with a highly abrasive slurry at speed, those panels are going to see a LOT of wear and damage.
Even "good quality" stainless steel can easily rust, as anyone who's owned quality kitchen knives will tell you. Some stainless alloys are more resistant than others -- but exposed to the right conditions they all corrode.
