I have done this experiment myself, and its been shown elsewhere, that a lit cigarette can't ignite gasoline. I'm not saying that smoking around gas is Okay, just saying its never been demonstrated to be a hazard. Lighting a cigarette with open flame around gasoline is.
A family friend ran a gas station in the fifties till the late 60's, and he smoked cigars all the time. He was also an accomplished hydroplane racer. I remember one time in the early 70's, when we were refueling his boat, the dock worker said to him you can't smoke here. He tossed off his expensive cigar in to the water and then just berated this dock worker in a way I have seen few other people ever berate someone else. But the New No Smoking Law was something the Dock Worker had to enforce. I felt bad for the Dock Worker: They didn't create the new law. And I lost some respect for this family friend, to be so rude to a person that was just following the rules set down, that THEY had to follow. I have noticed that older, all metal gas cans, now carry a premium at yard sales.
