You would be surprised, we now have plastics that match the mechanical properties of cast aluminum while being A LOT more corrosion resistant. The thing holding these back has always been production costs, but that has dropped drastically in the last decade. I went to school for engineering and don’t have concerns about vehicles starting to use plastic structural components.
”Plastic” is not a specific material but a VERY broad family of materials. Some plastics have weaker properties than a sponge while others are stronger than many metals. For example polypropylene (Easter egg plastic) is quite different than a carbon fiber reinforced PEEK, which exceeds the structural properties of aluminum While being way lighter.
