Car+ Semi = Ouch
A picture's worth a thousand words:

This was my previous car, about a year and a half into ownership.
Basically, I was in a lane that became an exit lane, a VW ahead of the semi merged ahead of me such that I couldn't move. I was in the truck driver's blind spot, and he hadn't seen me while I had been driving. I was just far ahead of him that he was in my blind spot as well. My first indication that he was merging was the sound of grinding metal as the ten lugs on the front cab wheel drilled into my door... 
Luckily, not too bad (door+quarter panel+wheel), and I reinforced my wariness of semis, even if they're being properly driven.
