You'd likely get by with dropping the match into gasoline most of the time too. Its not definite that there will be vapor from it in the right mix for it to catch fire before hitting the surface.

Gasoline also isn't quite as combustible as people imagine.

It's worth noting that hydrogen fires burn bright and quickly, but tend to not be very dangerous to people.

Gasoline and batteries are heavy and tend to stick to surfaces (including people) when they burn, almost like napalm. Hydrogen rushes upwards, away from people and surfaces, as it burns, and is generally quickly exhausted.

I strongly disagree with this statement.

I'm not sure what there is to disagree with. Fire around gasoline is dangerous for a number of reasons, but liquid gasoline pooled just isn't as volatile as people imagine.

The vapors are different. See both sides of this coin here: https://www.youtube.com/watch?v=DsZOE1nvlhI

Also, this: https://www.youtube.com/watch?v=vln5-HZpgcA

Don't try this at home. Vapors can change things dramatically and horribly. The videos lightly demonstrate this too, but it can be worse.

Liquid gasoline without the present of vapor is pretty much nonexistent. Dropping a match into some is going to be a problem.
