Early twenties, following two mates on our motorbikes.(here we go )
A45 near Coventry, dual carriageway. The two lanes were closing to one in roadworks, mates were ahead, I decided to go for it too.
The lanes were narrowing, I passed one, two, three cars, came alongside the last car as the lane was about 1.5 lanes wide, and this car inexplicably veered over towards me. Left me nowhere to go.
I was doing probably 80mph, and my right hand clipped a sandbagged roadsign, I felt an almighty smack to my body. I weaved and pulled over to the side of the road about 100 yards further down, the car carried on, it's driver still oblivious to my presence.
I had massive pain in my right arm, and then I noticed some blood on my hand. Looking down, I had lost my right finger just above the knuckle. I later worked out that the sign had hit my brake lever, the lever had sheared and the sharp end had cut my finger off.
I hadn't noticed it due to the pain of a compound fracture to my right arm. My glove was on the road, with my bit of finger still in it being run over by cars.
All of this was stupid but, the lucky escape part was, that on later inspection of my bike, I had a massive vertical dent in the side of the petrol tank. This means that at 80mph, my front wheel had turned past full sidewards lock and then back again. By rights, I should have been under that line of cars...
