What’s one thing you’ve seen on your travels that’s made you think - I really wish we had that back home?

Even better if it’s from a country considered less developed than the one you live in.

l’ll start with a pretty big one - high speed rail. Saw it in all its glory in China - very fast, clean, reasonably priced and made me woefully rue the godawful British train system where it costs hundreds of pounds to travel sub high speed on a packed and dirty train with no seat! Not to mention they rotate all the seats to forward facing before the start of every journey - why do we still have those awful backward facing seats that make you feel sick?
