Contrary to popular belief it's actually quite hard to ignite petrol except with a spark. Even then it only really fires with vapour close to the air to fuel ratio of 11:1 by weight (that's an awful lot of air).
Petrol landing on a hot surface evaporates almost instantly, it doesn't ignite. The vapour will ignite if there's a spark.
Much more likely to ignite on a hot surface is oil and especially brake fluid. They ignite from the heat before they are fully evaporated.
A lot of car fires were caused by brake fluid being spilled onto a hot surface after an accident. For a long time brake fluid resevoirs were often not mounted securely, that's since been rectified.
