Anyone who has taxied a 744 knows that the nose wheel will skid a lot in corners, even in very light damp conditions. If you’ve ever taxied an airplane, and it starts skidding on ice there isn’t a lot you can do. Selecting reverse, stamping on the breaks, or trying to power out of it isn’t assured to save you.
In these circumstances probably best to just get a follow me van and max speed less than 5kts. I hope the guys/gals keep their jobs.
