I did it once. On a bicycle, downhill behind a truck. I was a teenager - not a defence really, but it helps explain.
Nothing exciting happened that day, but a friend had a serious bike accident a week later under much more benign circumstances, and that made me stop and think a bit.
Seriously, the brain development curve where risk assessment gets wired in years after the body is physically an adult is a bug. “Intelligent design”, my arse.
