Same kind of locking wheels in Germany. I’m often surprised how the cart won’t move once you get onto an escalator.
The Menards (like a Home Depot or Lowes) store in Eden Prairie, Minnesota has this. There’s a magnetic lock, the wheels won’t turn. Pretty cool, actually.
It looks like the problem was that the wrong kind of cart was being used, the one in the video was one of those heavy duty, almost industrial, type flat bed carts, not a shopping cart.
