I don't think we know what it _actually_ detected these events as. Gizmodo is reporting car crashes, but I don't think there's any way for them to know that. The actual setting for the apple watch calls it a "severe crash" and has triggered for people crashing bicycles and things. There's also a separate "fall detection" setting that will call after a hard fall if you're not moving.
