Having recently moved to Australia I have struggled with shopping trollies with rotating rear wheels.
I hoped that its just nostalgia and that after some time I would look back and think :"actually rotating back wheels are a good idea."
It has not happened yet and this morning I read a brilliant description of trollies with rotating rear wheels
Right: Supermarket trolleys with fixed rear wheels
…elected to have all four wheels steer. This has the great benefit of making the device able to travel sideways, or diagonally, or through time, or across dimensions, with the only side effect that it cannot be deliberately moved in any direction whatsoever…
Perhaps its time to look at making clip-on guides for shopping trolleys rear wheels
Bunnings have some shopping trolleys with fixed rear wheels, and honestly they’re kind of a pain the buttinskie. If you’re going down an aisle and you come across boxes, you then have to backtrack, find a new direction and try again. I find that having all four wheels rotating means that the trolleys are easier to move, and navigate.
