I have seen some with very thick cables. Gas hoses are still thicker (though not full of copper). I'll allow that the heaviest plug I've ever come across may be slightly heavier than the lightest gas pump nozzle I've seen. But most pump nozzles in California are big hefty things with some kind of vapor capture system. Filling up your car doesn't subject you to a facefull of gasoline fumes the whole time. Unlike a gas station I had the misfortune to use in Illinois.
