I was driving along down a nice sunny A-road one day at about 60mph and I thought it was a bit quiet in the car, I'd left the radio faceplate in the locking centrebox on the car. Went to open the box and I'd obviously been careful parking my car in the middle of nowhere, so I'd locked the faceplate in the secure centre box.
I was on a long straight-ish downhill at the time and I thought, it'll only take a couple of seconds to unlock the box with the ignition key. So I stuck the car in neutral, turned off the engine, pulled out the key and stuck it in the centrebox lock. All going great. As I lifted the lid I went a little off line so I turned the steering wheel a touch to correct and 'click'....the steering lock engaged.
