Gas pumps are something you’re doing “right now”, so you ought to remember. Vs a charging cable s something you plugged in last night and left that way. Much easier to forget.

You’re very unlikely to change drivers at a gas pump so you probably won’t forget. Vs a charging cable is something your spouse may or may not have plugged in last night, and they’re not necessarily there to remember.

It’s been a long time since I’ve seen a gas pump with trigger lock. You have to be actively involved with pumping gas, holding it the whole time, so unlikely to forget
