I had the interesting experience yesterday of having the steering wheel in both hands but no longer attached to the steering column.
Fortunately the road was clear, dry and flat and the 5 speeder stayed in a straight line under hard braking. I think I had just got into 3rd gear so would have been doing 30+ mph.
The quick release fitting came off once before but this was at low speed and I thought, being new to the car, that I might not have put it on properly. Ever since I have careful to tug the wheel to make sure it is secure. I do find that it takes several attempts before it won't come off. Has any one else experienced this?
