Quick thread hijack sorry.
Being an ex-Metro driver, I was very used to getting them around without any nosewheel steering. Just using a touch of differential braking and asymmetric thrust. I made sure anyone new on the POS was also used to getting it around that way, as sooner or later they too would lose the nosewheel steering.
What's the story with Saab's? Can't they too be given a little direction with brakes/thrust?
