I was running for my train. After entering in the station airlock, for a reason i still can’t explain, i turned right instead of continuing straight ahead and BAM, i hit a glass with my face. Now i have a little scar, fortunately hidden behind my eyebrow.
Motorcycle training course had a section where you drive fast and when they drop their hand/blow a whistle you emergency brake. Then they check stopping distance. My old bike was front drum brake, the course bikes were modern with front disc. I clamped the front brake too hard and supermanned over the handle bars and broke my wrist. I did the rest of course (4hours) with a broken wrist because ending early would mean signing back up on the waiting list. At the end of day you sign your licensed. I could barely write.
Still better to learn that on the examination course than on the road.
Yes, I was very aware of brake modulation after that. Rode in snow and ice over the years, where careful braking was important.
