Not bad driving, on the contrary in fact. Driving up the M6 at a steady 50 or so in the managed section to the north of birmingham and the luton van (3.5T or 7.5T.. I know not, it wasn't too big to be fair) in front and to the left of me (lane 1) had the offside rear tyre deflate rather quickly.
The driver caught the van from it's swerve almost immediately and then got it over to the hard shoulder and appeared to stop it safely, my view was impaired as I had continued with the flow of traffic.
Most impressive piece of driving, I thought it was going to just swerve into lane 2 and hit the car in front of me. Shocked me a bit I have to say - although the driver in front didn't even brake or take evasive action, I wonder if they were oblivious?
Edit: This kind of van:
