A cigarette has the potential to light a pool of gasoline but just doesn¢t
have enough sustained heat. Gas ignites between 500 °F and 540 °F, the
cigarette at its hottest was between 450 °F and 500 °F but only when it was
actually being smoked. An ignition is very improbable.

The pool is the other part. It isn't so much the heat. When the
cig is in the pool, the vapor concentration at the ember is most likely
not right to light off. There is really not all that large of a range
when vapor isn't too rich or too lean.
