I'm pretty sure most places outside the US just use the huge metal trough that the US seems to reserve for stadiums

I'm from Ireland but pretty much any country I've been has all been automatic urinals

I live in Belgium and the last time I remember having to flush one of these was at least 10 years ago without exaggeration

I'm from Australia and it's been like 8 years since I've manually flushed

It's not even upgrade, even twenty years ago, most of them were either always rinsing or on some sort of intermittent timer. I guess when they were just a big communal trench it didn't make sense for them to be flushed by an individual. (UK / various Europe)

I have never seen a manual urinal in Britain. Never.

In the UK all the urinals in the bathroom will be flushed automatically at the same time using an auto-syphon that is attached to a tank that's slowly and continuously filled with water.

So it requires no moving parts or electricity, and flushes automatically at a regular interval depending on how fast the water supply is.

And it's been that way basically forever.
