Modern cars are a marvel of cheapest manufacturing and materials. What would we accomplish if we optimized for corrosion resistance? It's not like we don't have the materials or processes. But they're nowhere as cheap as stamped sheet steel.
- throwaway0a5e 5y agoThe "primer" step for car bodies after they've been welded is (typically) already a dunk tank. Hot dip galvanizing would only be a marginal increase in cost over that. You can't easily paint over that and people want cars in all sorts of colors and they last "long enough" as-is. Some smaller under-body assemblies are galvanized or zinc plated before paint.

- driverdan 5y agoEverything about modern cars, except for touchscreens, is superior to past cars including corrosion resistance. A five year old car from the 80's in an area that used salt and sand would have rust holes. A car from 2012 doesn't have anywhere near as much rust now. My first car was a 13 year old Toyota Tercel. It had literal 8"+ rust holes in every door, the frame had rust holes, and the fenders were falling apart from rust. My second car was a 10 year old Cutlass Supreme. It had a 6" rust hole one door, a rust hole in one fender, and plenty of other rust underneath. This does not happen anymore, except maybe trucks used for salt.
