Probably more than a few times! Happily none resulted in anything quite like your tale, but then that's more down to luck than good judgement at the time!
Not me, but another biker confessed that he thought he knew it all, that he was untouchable. He went to overtake a line of traffic, dropped a few gears and went for it big time. He never thought that the car stuck right behind the slow vehicle at the front would pull out for an overtake, but it did....
His bike was written off, and he had more than one broken bone.
I met him an an IAM social ride out - It took that accident to make him wonder if maybe, just maybe, his riding wasn't actually as good as he thought it was, and maybe he could learn to ride a bit safer....
A philisopher once said that humans are the only animals on earth capable of learning from others mistakes, yet are curiously unwilling to do so.
Biggest difference for me now vs my 20's - despite another couple of decades experience on the roads, I finally accepted that I probably could do to learn a few things, and then I realised that I'd NEVER stop learning
