Last (first ever broken bone) major crash I got taken out about as intentionally as intentional gets. Although an unrecoverable impact (at least for me), I understand what happened (guy swerved sideways at 30 mph on purpose). No yips.

The one shortly after I turned back to check for cars just as my teammate slammed on the brakes. My fault. I look back a bit less now. No yips, but some close calls in groups of inexperienced riders.

I've also fallen hard in (flat) turns, descents (turns and straights), etc. I've had blowouts on front and rear and both, at high speeds. I've had spokes break, due to stuff hitting them or due to plain failure. I've made a conscious decision to stop using a fork or frame or bars or stem or wheel or tire or cable or brake etc etc etc because I no longer trusted them. I know that if my fork failed I'd be on the ground really fast so I try and make sure that that doesn't happen.

I back off when I feel uncomfortable too, so that's my personal thing. Maybe those are yips, just so automatic I don't think of it.
