By the way, the start of this thread is the story of me driving a van under a low bridge and taking part of the roof off... Just to clarify, I did approach the bridge (or tunnel as it was quite long!) very slowly so that if I was too high, then I'd just touch the bridge and would simply reverse out... after getting past this initial test stage and finding myself inside I then went a bit faster, aware of the traffic behind me... what I didn't realise was that about half way through the height suddenly reduced by about 6"... and it was dark in there!! This is where I heard the almighty crash and the van came to a halt... so I blame the bloody stupid bridge design!! Another example of the power of assumption! never assume that just because you're in the start of the tunnel that you'll get out the other side unscathed!
