I always walk by this one grocery store and always see shopping carts lined up just before the end of the parking lot as it seems people really think the signs stating the wheels will lock is just to deter you from trying, but how does it work? My only guess would be magnetics but even then I still have no idea how that all works but I find it oddly interesting.

EDIT: Just to add on, I live in Ontario Canada. Not all businesses have this sort of thing but a lot of the bigger companies do. And yes, they are in fact real, I’ve tried to push one before, those things don’t move AT ALL once they’re across the line! Quite interesting.

Sometimes you have a moving walkway in your trolley store. We have them in IKEA and our local big supermarket. Wheel the trolley onto the ramp, brakes engage. Reach end of ramp, brake is released. They seem to do it hundreds of times a day without complaint.
