I'm from the southern US. Driving in the UK during a visit was a revelation. The best part was that drivers actually keep left except to pass. It makes driving so much nicer. That and using signals properly.

I didn't try driving in London though.

I was surprised by this comment, because UK drivers are actually pretty bad at keeping left on the motorway.

Motorway driving is not part of our driving test, so you can qualify without ever being shown how to drive on a 3 lane road.

It's not uncommon to see people cruising along in the middle lane, completely oblivious. Drivers are noticeably better at keeping right in continental Europe.

Well it helps that undertaking is super illegal here.

It hasn't been illegal since 1972.

It's discouraged in the Highway Code and an enthusiastic traffic officer could (but almost certainly won't) charge you with careless driving.
