And it'll just piss off customers too. It'll be like self checkout which took the better part of a decade to make even vaguely work well. Endless issues with children climbing on the carts, people putting purses in them. How do you accommodate different bag types over such a large scale? What if part of the cart is broken? Are you gonna tell me that every single cart is going to be within a dozen or so grams that these scales will be accurate to? Will each cart be weighed? If so you'll have to attach some kind of barcode to it. What if that falls off? How will you deal with the machine seemingly not working at that stage then telling a customer that they have to switch carts.

I'm so glad this shit is considered kidnapping in the US.
