I have a cousin that is part of law enforcement (he’s sort of like boarder patrol) and he said that while shadowing a superior that he learned that, because of his job, he should pump gas with his car on and it had just become a habit for him. I thought that was a big no no for fire hazard reasons. What else is bad with that?

Common belief is that it’s a fire hazard, but that’s not true. The only thing that’s exposed to the air that’s hot enough to ignite fuel vapors outside of the combustion champers would be the catalytic converter, and that’s only inside of it. So the chances of your catalytic converter creating a fire due to filling up with gas while it’s turned on are pretty much zero. The biggest cause of gas station fires is static electricity. If you want to be safe, just discharge yourself by touching something metal before you touch anything near the filler/nozzle.
The only reason you should turn your car off is to save fuel. There’s no reason it needs to be running while you’re not in it. You’re just wasting fuel.
