I have to say I completely agree with RunnerDuck. I just can't see this as a huge risk when done sensibly. I put the carseat in the front of the cart with both kids and never had an issue. Some carts were, of course, CLEARLY unsafe because of the angle, lack of fit, didn't lock, etc. and in those cases I put the seat in the basket.
I get that some people have zero common sense, but I think a LOT of baby gear is potentially dangerous if you don't use common sense.
