A few years back Richard Hammond (the short former Top Gear UK) presenter did an experiment with this on another British show of his called Braniac (a sort of light entertainment popular science show) where he filled a caravan with petrol and fumes and attempted to get it to ignite through static electricity (they did lots of different ways of generating it).

They couldn't do it and even when for the laughs they decided to blow it up with a match it still didn't ignite.

The fuel air density has to be a certain ratio. This is why you have complicated systems to inject just the right amount of air and gasoline into the pistons. I would guess that since it is much harder to combust liquid gasoline is would be much harder to combust a very heavy gas/air combo.

Probably best to not use entertainment shows as a metric for safety.

Mythbusters also did experimenting with static and gasoline vapors https://www.youtube.com/watch?v=VjrkwxMhc4s
