Dozens. #1 most obvious atm is autostop. Starter gives you enough juice to enter the intersection, but engine sputters and you get tboned. Same for not providing enough acceleration/ hp. Also 1 pedal driving. Electric cars that outweigh the 'old' 'inefficient' light trucks because batteries are heavy. Harder to stop, more wear on roads. Tires that are designed to extract breaking energy over stopping. Lithium fires (not cause but much more dangerous result). Aluminum crush zones in cars not big enough to have crush zones. Every design decision is a compromise.
