Especially when inconsiderate people leave their trolley in the middle of the aisle, so even if there was 2 metres, you couldn't get past anyway. Quickly walking past someone is safer than being stuck in the aisle behind someone. 

If people aren't going to follow them, what's the point in implementing them. I think the one way system at my local ALDI lasted about a week before it was removed.

You've disagreed by echoing my point really. The failing is people that are too ignorant or think they know better than to use them, not the system itself.
