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.
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.
