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

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.

There are enough standards that don’t have non-metric alternatives like the square drive of socket wrenches or a lot of bicycle standards. It’s very unlikely that they will get replaced

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 countri…

> It would be way more annoying for LHD countries to change to RHD As a complete aside, 1 country has done this: Sweden on 3 September 1967 and "It was by far the largest logistical event in Sweden's history" https://en.wikipedia.org/wiki/Dagen_H

Iceland did it a year later, https://en.wikipedia.org/wiki/H-dagurinn, but since there was less then 200k people living there it was a much less dramatic change

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 a…

The US has a 240 volt electric system nearly everywhere. The exceptions are some industrial factories that get higher voltage. There might be a handful of houses that haven't upgraded their electric system since the 1950s that are still 120volt only, but that is very rare (I've heard of it, but never seen it). We use 120 volts to outlets (120 is half of 240), but the system itself is 240 volts.

Using total population is a bad metric considering India itself has about 2 out of 7 billion people.

Why wouldn't Indian people count?

it's arguable the "much of the rest of the world" could refer to number of countries rather than number of people, but I think "much of" applies to both so the author avoided the confusion.

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 t…

The US uses the metric system in some places, but that is not to say it is "on the metric system"- after all, all road speed limit signs are still in miles per hour, as an example. Fuel is priced in dollars per gallon. Consumer goods are almost always sold in measurements of pounds, ounces or gallons. People are measured in feet, inches and pounds on their ID cards and at doctor's offices. Metric has made almost no i…

I believe their point is that a mile is defined to be exactly 1609.344 meters, a gallon is defined to be exactly 3.785411784 litres, a pound (mass) is defined to be exactly 453.59237 grams and so on. These are all just weird multiples of metric units at this point.

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…

In the eastern parts of Russia (well even in "central" Russia like Novosibirsk), there's a lot of imported Japanese cars from their second-hand market. These have the wheels "on the wrong side", but nobody cares, they still drive on the right.

The imperial system America uses is better optimized for quantities people expect to use in real life frequently without requiring awkward decimals or larger numbers etc. better ergonomics. metric is only for science.

With imperial you have weird fractions instead of decimals. To know that 3/4“ is larger than 1/2“ I have to actively think, decimals come pretty naturally (which was probably different in times before people went to school and learned to do math on paper)

Electric distributon costs less because less copper/aluminum. 120V exists because the US is plagued by lawyers.

Eh, I seriously doubt that we will be changing the distance a mile represents if, for some bizarre reason, a meter gets redefined. Likewise, pounds and gallons and so forth. These measurements "defined in metric" is really more of a "formal conversion rate" ala converting between degrees F and C.

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

It's called a Diverging Diamond https://en.wikipedia.org/wiki/Diverging_diamond_interchange

This is kinda like that point where Hong Kong (RHD) traffic meets mainland China traffic (LHD) IIRC. You have to do a little dance to get everyone on the same plan.
