Most drivers in the vid were sliding hown the hill brakes LOCKED. ABS was fooled into thinking the vehicles were stationary yet all 4 wheels were sliding.

Drivers need to learn that in order to re-activate ABS function, the brakes MUST be released for an instant so the ABS system gets a signal from pulse sensor/starwheel and "sees" wheel rotation.
