After fueling the car I was distracted and failed to remove the nozzle from the tank filler. As I moved forward, I heard a thump and stopped. The fueling hose was pulled from the filler and was also disconnected from the gas pump. There is a quick disconnect on the hose that parted. Evidently enough people make the same mistake otherwise the quick disconnect would not have bee provided. The station attendant said not to worry it is easy to reconnect. He said I was not the first person to do this and won't be the last. There is an easy remedy to prevent this from happening. All cars should be equipped with a sound waring indicating that the fuel hose is still in the filler. Even better there should be an interlock to prevent the car from starting. This would not be a very expensive warning device. It certainly would make more sense than having the windshield wipers come on when rain is detected.
