Yes, one of the lasting legacies of empire.
NA has gone through various evolutions: getting rid of 25Hz, getting rid of DC mains,
requiring grounded outlets as standard, in my jurisdiction (for example) distribution
('pole-top') has evolved from 12KV to 25KV, etc.
The split-phase system may be the oldest but for residential use it's quite elegant
and efficient. 3-phase is there for where it's needed, commercial or multi-unit
residential buildings, it's done for smallish pump-houses within residential
neighbourhoods. In the big picture I haven't seen anything to suggest an overall
benefit to changing to some other system.
One could well suggest the reverse, that EU move away from that "highly
dangerous" 240V system.
Oh yes? as far as I know that is the Voltage most countries in the world
use ... and the americans in their split phase system too.

As I said, with the split phase-system you have 240V available but not more than 120V
between you and earth.
There's a big difference there compared to 240V to earth.
(The neutral/common is bonded to earth in the EU, isn't it?)
I don't wanted to kick you to convert this now ...

going to sleep now, it's 11:27PM here..
