I was always worried something like this could happen :-

Makes me wonder how often it really does happen.

Perhaps some places are more careful than others...? ;-)

Never seen a rolling road in the UK that was not set into the floor. And the operator drives the car.
Rare to see folk allowed to stand that close, too. Just suppose car had come off on the other side.
Incidentally, a dyno is usually referring to an engine dynamometer not a rolling road in the UK. IE just a engine.

That's a vehicle dynamometer as opposed to an engine dynamometer.It is good practise on FWD vehicles to apply restraints to the front end of the car to stop it coming off the rolls-it is also normal to build up the speed slowly.Some vehicles are naturally stable on the rollers-others try to move.Old dynos used two small diameter rollers,later ones two larger diameter and now "state of the art" is a single very large diameter roller.And,as said above,usually everything is set in the floor.
