I had the opposite experience last weekend. I didn't crash when I thought I was about to. I've taught myself to never let go of the bars if I think I'm going down. Last weekend I hit a pothole at about 22 mph and my front wheel bounced so high I was sure I was going to flop over, but before I even knew it consciously I was able to get the bike back in control because my hands stayed on the hoods. Whole thing took less than a second, but in 50+ years of riding, I've never experienced such a recovery of a clearly out of control trajectory.
