You brake hard, rear grip goes to zero, and you fishtail. Then you have to reduce braking force or you crash. This doesn’t happen in a car because unloading 2 independent tires is very hard.
You touch loose gravel going through a corner, front loses grip, you crash. Hitting the same gravel patch with 2+ car tires is unlikely.
They had a bike that was equipped with a roll-cage, like an exoskeleton that prevented it from actually flipping but did allow it to lay over enough such that it would. Then they sent the bike through excessive lean angles across slippery surfaces.
The riders who adjusted for the slippage wrecked, the ones who just allowed the bike to fish a little didn't.
Of course that's assuming you aren't too close to the threshold, etc.
But it was eye opening to learn to just kind of hang on and trust the machine a bit.
Luckily insurance paid for bike damage and new gear. I only got a bruise where my elbow missed the elbow pads. Bike stopped maybe 50ft down the road.
