Both times it didn’t go off I was on my bicycle. I really thought it should have.

Once, one of my pedals striped out of the crank, as I was out of the saddle hammering. When I lost the pedal on a downstroke, I basically threw myself into the pavement. Apple Watch didn’t go off.

The second time, I collided with another cyclist, as I was avoiding a pedestrian.

The crash/fall detection has never worked for me. I do have it turned on, but the two times I think it should have gone off it didn’t.
