Robot shopping carts to annoy Limeys

Since people apparently can't be trusted to make intelligent decisions on their own, British shopping carts (called trolleys over there in that crazy language they speak) will soon begin hectoring them about various issues:

Supermarket shoppers may soon be cruising the aisles with "intelligent" trolleys that warn them if they're buying too much junk food, technology experts say.

While many would be happy enough if they could simply get their trolley to go in a straight line, the high-tech model will be fitted with a computer screen and barcode scanner.

It will read each product's individual code to give customers information about calories, nutrition, ethical sourcing and the environment.

Um, who exactly is going to decide which products are "ethical" and which are good for the environment? I'm going to go out on a limb and guess left-leaning government bureaucrats.
