normally Europeans keep to the right

This clearly demonstrates that, should the United Kingdom ever re-apply for membership in the European Union, not only will it have to adopt the Euro and the metric system, but also switch to right-hand traffic. 🙃

So why not implement signage?

Shared paths (pedestrians and bicycles) have clear directional markings here, which I expect would solve most of the problem.

As someone originally from Hungary: as a kid I was taught I should walk on the left (if there is no pavement), so I could see the cars I'd be sharing the side of the road with. So technically it should all be reversed everywhere.

Also there is no consistent walking side tendency anywhere, and just walking to/through the shops you'd know that. Brits might do a queue but see if you can predict which side they'll be walking on, and it's no different elsewhere.

Dear all of of the United Kingdom:

You do not get to make jokes about imperial vs metric measurements while still clinging to MPH nation wide. The rest of the world thinks you're fucking stupid.

Further, the majority of the world walks and drives on the right. Figure it out.

Finally the 2nd floor of a building is floor 2. Not floor 1. This is not even up for debate, nobody agrees with the UK on this absurdity.

This has been a public service announcement.

I've never heard of driving side ever applying to walking side. What happens in places like France or Sweden where trains run on the left and cars run on the right?
