Gas doing 2 of those 3, and diesel only 1.
Not assuming it would be the same, but picturing a spill at a gas station. Spilling gas is a problem, but at least it's just sort of there. If you get an ammonia leak and it forms a vapor cloud, I don't think most people would know how to deal with that. I'll bet your spilled gas likely won't migrate into the intersection.
But on the plus side, we already see what handling/transportation of large amounts looks like for agriculture, even if rail carriers etc. dislike dealing with it.

It does have a higher ignition point than gas. But one a spark can definitely reach. It’s been a common problem in industry where ammonia gets used a lot (refrigeration in particular).
BLEVE’s are also a problem too of course. And the toxic nature of breathing it in! Haha.
Edit: Maybe methanol?
However hydrazine is liquid at room temperature and it can be converted to hydrazone (also being considered for fuel cells) which is solid at room temperature and non-reactive... until it comes into contact with water at which point it all turns back into hydrazine.
But yeah no there's really not a "nicer" fuel. Generally, if it has nitrogen in it and it isn't literally just nitrogen with itself, it's dangerous. And the more nitrogens it has the more dangerous it is.
Urea maybe? It’s almost non toxic and is 2x ammonia + a carbon monoxide molecule.
though not sure how efficient it would be to extract energy from.
Speaking of ‘extra nitrogen’s are generally bad’, a callout to the azides!
I have extinguished a fire with diesel.
It isn’t as easily flammable as gas, and doesn’t have easily autoignitable vapor like gas.
I’m guessing you dumped a lot of it on something without a lot of thermal mass?
If you did the same on a bonfire, you’d have a different story.
