I think that the difficulty with guiding a shopping trolley is in the fact that all 4 wheels swivel. If the two rear or two front wheels were fixed in a forward direction then this would give better control and sideways or uneven pressure to the trolley handle would be directed towards turning it.

becuase they way it was built try to check their wheels you can push or pulled it in every direction that you wanted.

They are not made to last.

because they are cursed

i like your questions....i wish i could just say "shut the hell up and let me decide"....whenever i'm out shopping with it
