I hope they do. There is an obscene amount of integral parts in automobiles that are made out of poorly formed plastics. Not only do a higher number of parts fail, the manufactures making replacements often follow the same flawed construction.

No 1940s vehicles didn't come with ABS, front and side panel air bags. But linkage in the suspension was at least metal, and wasn't known to fatigue every five years. If I were so inclined I could bring my hick mechanic in here and he would have volumes of corner cuts to cite that have resulted in unnecessary deaths over the years.

Some advancements have been great but overall legacy parts don't engulf vehicles in flames. Hodge-podge workarounds do[1].
