Sometimes, rarely, you find a bit asphalt in Brazil where you have to drive on the left and often it is signalled as "mão inglesa", which is something like "English flow".
Recently I discussed with some friends the relative merits of LHT and RHT, and we came to the conclusion that LFT was better because you could drive and shoot with your right hand. So LHT is great for drive-by-shootings. Curiously, no alcohol was ingested during this conversation.

That makes it sound like Britain is the only place with left side traffic. 35% of the world population live in countries where they drive on the left side.

one of cool road signs I saw years ago in Ladakh state on road from Manali to Leh. Funnily enough that 19h minibus trip sometimes went through valleys without any form of road, just used least uneven path. Not so funnily enough we had an obvious technical stop later when driver was banging with huge rock on some part of suspension for an hour, and luckily his caveman engineering worked well enough to get us moving again

There are some spots in the US where you drive on the left, albeit for a short distance and the road is divided. Still messes with my brain. E.g., here in the northern suburbs of Detroit (W. Big Beaver going under I-75): https://www.google.com/maps/@42.5620634,-83.1581674,18z

Bit of a stretch... It's a dead-end private road, also sometimes called a driveway, where the owner has their own rules for how it should be used.

London will switch sides when America goes metric - i.e. never.

The US is on the metric system: The official definitions of US customary units are in metric.
For example: https://www.regulations.gov/document/NIST-2019-0003-0001
> After December 31, 2022, any data derived from or published as a result of surveying, mapping, or any other activity within the U.S. that is expressed in terms of feet shall only be based on the “foot” equal to 0.3048 meter (exactly), formerly known as the “international foot” in the 1959 Federal Register notice.

It would be way more annoying for LHT countries to change to RHT than to switch from US units to metric, have to change literally every road sign, street light, road markings etc in the entire country.
Plus everyone would then be driving cars with the steering wheel on the wrong side for decades until the whole fleet got eventually replaced.
Countries have done it before, but I think there's a reason not many countries have done it since the mid 20th century when roads and cars were a lot simpler and there were fewer of them.
Switching to metric could be done gradually - replacing existing signs with metric ones only when they wear out, building new systems in metric while still using US units for the old ones.
There's no way to gradually switch from LHT to RHT, you have to somehow do a switchover in a day

And the US and various other countries (like the UK) effectively use hybrid systems for units for many purposes. Science and engineering in the US are heavily metric.

Once all manufacturing is controlled by China, they could refuse to make cars with steering on the right or use Standard measurements, increasing pressure and eventually forcing the UK and US to switch.

Thank you for informing me that China is likely to take over all manufacturing when it comes to cars. I am appalled that there are no US, Japanese, South Korean, Indian, Vietnamese, Russian, or any other nations that manufacture cars.
It also sounds completely plausible that a binary choice like left hand or right hand driving can be switched in a way that drives a pressure campaign that nations will give into China on because it’s an easier short term choice and wouldn’t gain an immediate reaction to due to the enormous cost that would be rapidly felt.

The US drives on the right (which is the right) side. So why would the US switch? Its really just Australia, Japan, India and the UK that drive on the left. The other 190ish countries all drive on the right.
PS Your 240V electric grid works that way because when the US switched to 120V (in like 1900 or so), we sold all our old gear to you and you never switched. So now all your electric things cost more as a result and your electrical outlets will kill you. So your decision making on such things is suspect.

I'm sure you know this, but for the benefit of those who haven't seen it before: it does not go anticlockwise. The"roundabout" in the middle is an illusion generated by the 5 normal roundabouts in a circle. There are no special rules.
It has a bad rep, but if you're used to British mini roundabouts, driving on it is a non-event. The regularity actually means it's simpler than other, smaller, but more arbitrary aggregations of mini-roundabouts.

So it accomplishes the baseline performance that just about every major intersection planned out in the last 100yr does of being navigable without serious confusion.
If it's so good why aren't there more of them? Not like England has any shortage of N-way (where N >4) intersections they could be used at.
The wikipedia page says "the roundabout provides a better throughput of traffic than other designs and has an excellent safety record, since traffic moves too slowly to do serious damage in the event of a collision" which to me sounds a lot like someone trying to spin failure to play up the silver lining.

It was designed by the Road Research Laboratory and has been measured to have better traffic throughput than the conventional roundabout it replaced.

I don't know why you expect me to be a partisan for it, given the best thing I said about it was "driving on it is a non-event".
Experimentation with junction design has been a good thing in the UK. Many of the designs are, however, attempts to do as well as possible in the space, because a better design would require compulsorily purchasing some people's houses or gardens. So, although there are not lots of magic roundabouts, there are lots of agglomerations of mini-roundabouts with slightly different topology , many of which are more annoying (but fit in the space, and keep traffic flowing).
However, it does seem likely that this is kept mainly because of its fame. I seem to recall that there was a proposal to replace it which was shouted down.

My first encounter with this was on a foggy November morning, and I had no idea what was going on.
There's another very similar but smaller one at Heathrow, next to the Hatton Cross tube station. That one has the added attraction of London taxis and Ubers traversing it at high speed.
