Every car at a gas station has an exhaust system with temperatures well over the ignition point of gasoline. If there was a problem we would have to let our cars tool for half an hour a quarter mile away from the pumps before we pushed them there by hand.
fortunately gasoline only burns in a narrow range of mixtures which are impossible to get in open air.
The concentration of vapours matters. It is still best to not be smoking above the nozzle (even if it’s unlikely to be a problem), and any embers or flames touching a small stream of it are still a problem. The safety precautions are over the top because the consequences if it goes kaboom are pretty terrible.
