ELI5: Why can't cars have a pull starter cord as a back up starter?
gpt
Car engines are huge and very difficult to crank compared to pull-starters. Your lawnmower might be 5 horsepower, but even your aunt's minivan is 120 horsepower or 24 times as big as the lawnmower. The lawnmower is hard enough to start with a pull - that van is gonna be impossible.
