But this is such a cool talk. My local Giant (grocery store) has a wire that goes along the left side of their parking lot. Only about 20 spots there but once you cross that line, the wheel locks. It took me 2-3 trips of confusion why the cart was breaking before a store employee shouted at me "you're gonna lock it" right as I crossed the line. He came out to me, unlocked it and we had a long talk about how it all works.
