Or the council car park at the side of M&S in Rickmansworth - that's
"wrong-side-of-road" as you go in.

A lot of multi-storey car parks are designed with the ramps between
the floors do that you go up/down the wrong side (ie on the right-hand
side) so that the two streams of traffic don't have to cross. Makes
you wonder why they didn't simply design the car park as a mirror
image to avoid this. At the very least, if you have to go up the
right-hand side, this needs to be signposted very clearly.

It's a flat outside carpark... In and out are next to each other, just the
wrong way round.
