-Countdowns on pedestrian crossings. I first saw these in China a few years ago and London now has a few. Why don't they have them everywhere though?

-Sanitising spray dispensers in toilets. We have these things in the cubicles at work that let you spray sanitiser onto some loo paper which you then wipe on the toilet seat. Why aren't these everywhere?

-Trams. Seems to be only Manchester with these. What's with that?
