TL;DR: Ask yourself if it’s worth being self-righteous about having done the right thing while lying in a hospital bed or your grave. This became my rule when evaluating the risks of doing certain things, even when I was “right.”
One was a guy who was training for Olympic trials in the US southeast. He was struck in the back of the head by the stanchion on the side of a boat trailer by someone who was legally blind in his right eye (the side on which this rider would be in the US).
The other was a rider who was killed when a motorcyclist lost control coming around a corner at over 100mph on an isolated road, struck him head on, killing both.
In both cases, irresponsible operators of motor vehicles where the rider did nothing wrong, and was riding where they were legally entitled to be. That said, both cases were relatively isolated “country” type roads with little to no shoulder. I used to frequently ride the road where my friend was killed by the motorcyclist. It was a really nice road to ride when fewer people lived in this part of the county, and lead to wonderful mountain roads. Now? You couldn’t pay me to ride that stretch of road. Too many cars, not enough room, and you STILL see tons of joyriding motorcyclists on that road in spite of the fact that multiple motorcyclists have killed themselves on that road in the last few years doing stupid things.
Sorry, derailing the thread… be careful out there, and make good use of your trainer.
