5 or 6 years ago I topped a hill on a mountain road going too fast and ran into a deep wash down the middle of the road. Before I could slow down, 1 front tire dropped in the wash. It rattled back and forth and jerked the bars out of my hands. Luckily I was able to get a foot on the rear brake and slow down enough to get control of the steering before it flipped me. PS would have kept the bars in my hands.
The moral: slow down, stupid, and get PS on the next one.
