He was stopped until he received instructions to cross the runway from the person whose job it is to sit in a position with good visibility and tell people when they can cross runways. He wasn’t driving fast at all. The whole system is set up so that vehicles with blind spots (every large passenger jet) can safely move.

We can’t say that emergency vehicles should just stay in on dark and stormy nights.
