It really takes a lot of prolonged heat exposure to ignite liquid diesel. Seems odd. Glad no one was hurt and all ended well, considering the circumstances.
That may be true, but when it is being sprayed at 55mph, quite a bit is vaporized and no longer in a "liquid" state. The auto ignition temperature of diesel is actually lower than gasoline.
Diesel is 410F
Gasoline is 477-536F.
the exhaust manifold at highway speed is typically 700-800F.

Not sure what 55mph has to do with anything but that's the low pressure side of the fuel system still (pre cp4) and is roughly 58psi, no where close to any atomization.
