Surely if these are important in boats, they’re doubly so on aircraft.
Um, no, the logic doesn’t work for that - if a boat engine stops on a lake, pretty much the boat stops and that’s about it. If an airplane engine stops, the plane crashes and people die.
On the other hand, given the number of idiots that get out of their cars, leave them running and have the car roll away because they’re idiots - well, maybe we should put that in cars too.
It took me a minute or so to stop laughing, that was genius right there!!
