Peloton keeps referencing a 'key' that should be preventing this. Is this like a lanyard on a jetski or other devices that you attach to yourself in case you fall which activates a kill switch? If so, does this mean that people are leaving them in during these incidents?

(I'm not going for a 'blame the victim' attempt, I'm just trying to figure out what it is that Peloton was first trying to use as their defense before caving)
