Yes. Gasoline fumes are either too lean or too rich to ignite "most" of the time. I've seen people put out cigarettes in a capful of gasoline.

I shook my head in disbelief when the warning about using cell phones while refueling came out. I'd think that the risk of staticky shoes creating a spark while removing the filler cap would far outweigh a cell phone igniting anything.

But, in our litigious USA, anything that could happen has to have a warning label...
