My treadmill doesn’t have a guard either. It does monitor the motor and if it suddenly stops it shuts down. I have observed an accident at a commercial gym where it also shut down on jam.

Example: Old coworker mentioned working on a controller for an airbag. She said the watchdog timeout was set to a shorter period than required to fire the airbag. So if the firmware went off into the weeds the watchdog would fire before the air bag.
