You can toss a lit match into a puddle of diesel and the match will go out. Diesel burns, but since it doesn’t evaporate as fast as gasoline, you don’t have those flammable gases hanging in the air. A trail of diesel that’s being burned at one end will not spread, unlike gasoline.
Gasoline doesn’t burn that easily, either. Cars with gas tanks don’t burst into flames while sitting powered off in a garage. Even when they get wrecked they don’t usually burst into flames.
On the other hand, gasoline is slowly causing the world to burst into flames…
Gasoline burns accidentally when fumes are released, as the stoichiometric mixture has to be pretty specific to combust.
Gasoline in a gas tank does not achieve this mixture. That’s the entire job of the fuel pump and throttle in modern cars. As the other user said, there are lots of sparks and live electricity in a car crash, it’s just not easy to set gasoline on fire or make it explode.
Diesel does not appear to achieve this vapor mixture readily at standard temp and pressure, like gasoline does, and therefore is technically safer in this specific regard.
You’re aware that diesel is quite hard to catch on fire
That’s why he said gasoline tho
But that’s not relevant for busses
No it’s not. It’s harder to catch fire than gasoline.
It still catches fire easily.

Okay

Well yeah… You need a spark to cause a fire. To have ignition you need oxygen, fuel and a spark.
Nothing burns easily if there’s no spark.

Okay?
There are plenty of sparks in a car crash.
Diesel combusts at 140 degrees. A care could reach those temps in a car accident as well if we’re making that argument.
