Green and lime

If you're visiting Warsaw you needn't worry about missing out on your Caffè Nero fix - except for some reason it's called Green Caffè Nero in Poland.
The things in the front of the picture are Lime electric scooters. You risk being run over by these things, usually piloted by shrieking teenaged couples, on most streets in the middle of the town. Still, I think they're a good idea; you unlock them using a phone app, ride to your destination and pay for distance or time. Apparently they're illegal in the UK at the moment, but I'm sure they'll catch on soon.
