Apart from when I was knocked off my DT50 by a hit and run driver I had a very close call on my old XL250
Riding along Seymour road one evening a car decided to pull out directly in front of me. The twat then decided it was best if he/she just stopped there (why do they do that??) completely blocking the road. I was only doing 30 and managed to just miss the back end of it's car by riding on to the pavement between the hedges and parked cars, luckily there was no one on it at the time

Luck and experience saved me that night
