armored trolly

I don't know about you, but sometimes, if I leave my trolley unattended for more than one minute, sometimes people mistake them for the discount carts and take things. other times the notice that the groceries i have placed in my cart happen to be close to what they are looking for, and just take the whole cart. other times, I get the really squeeky or dented ones that are outright ugly and may even have a few diseases causing fear of infecting the groceries. so I propose that carts have have heat sensing hadle-bars to detect when the shopper leaves the cart, after 15 seconds of alone time, the wheels lock up, and a top folds out to cover the groceries, and armor on the corners to prevent dings and possibly wheel trouble (possibly even a wheelie bar to prevent immature shoppers from popping wheelies in a supermarket, like me a few years ago...), a teflon coating on the bars to prevent snagged grocery bags when removed from the cart, a self cleaning system ( sprays alchohol on inside to kill germs, lysol maybe...) and stronger wheels with wheel gaurds to prevent bending and squeeking, and finally, the one thing that everyone must be expecting based on my previous posts- optional .50 caliber machine gun.
