Steering shaft twisted?

[dom14]

So I saw on fb last night a steering box output shaft of a gq snapped..
Never seen it before but there was a few comments of people who have had it happen to them..
Hopefully it wasn't the OP.

Yeah but, what are the scenarios you can think of that could happen?
I mean, if the output shaft can snap easily, that can't be a good thing, can it?
Loosing control of a vehicle 'cos of something getting stuck near the steering output shaft at high speed & snapping it,
is bit scary.
