Completely different, 540 degree away, strategy here. At any moment I am ready to jump off the bike and let the bike fall under me, escaping without any bruises. In winter your control over what you are riding on is naturally limited and the bike will slip occasionally whether you like it or not. The key is to make it an irrelevant event. When I was young and dumb, I used toe clips and straps - all now eradicated.
I’ve had 40+ years of winter riding experience and I’d really like to know which direction you take to “jump off the bike”? Do you jump up? Sideways? Off the back of the bike? Of the
front of the bike? All of those have major issue, not the least of which is the bicycle itself.
Paraphrasing here: winter crashes tend to be unplanned and instantaneous affairs. I’m not sure what you mean by making it “an irrelevant event” but when I feel my bike slip (if it happens in slower motion than most times it has happened) I try to stay upright but if the bike is going to fall, I stay with the bike and let it take most of the fall. A broken or bent handlebar is cheaper and easier to fix than a broken leg, arm, or wrist.
