You drove and pulled up to the gas station to fill your gas tank. You exited your vehicle, opened your gas tank cover, grabbed and put the dispenser nozzle in. You also had to pay at some point.
How can you forget that the hose is still connected to your car when you drive off?
I think it’s only New Jersey now. It used to be Oregon also but I think late last year they removed that requirement.
You are correct that it is no longer required in OR but many places at least still offer it as an option
