It is misleading to compare Avgas to petrol, diesel and Avtur in one go - Avgas and petrol are both far more likely to ignite than diesel or avtur.
I think it was Freddie Laker many years ago who challenged someone to stand in a pool of JP4 while Freddie stood in a pool of avtur, and start lighting matches!
