For someone so ready to leap to conclusions, you don’t sound particularly informed about British attitudes to road speed (notably, Britain still uses mph, not km/h). You might be surprised to discover that outside built up areas in the UK the national speed limit on an undivided road is 60mph. Not an undivided highway - an undivided road.

Here’s an example of a random British B road with a 60mph speed limit: https://goo.gl/maps/2jetrMeoWbuTvShN9

Most of my experience is on continental Europe, where it seemed like multilane highways topped out at 55-65 km/h. So you're probably right.

No need to go on the offensive though. "Gaol" is a pretty dead giveaway of Britishness.

Sorry to burst your preconceptions, but... no, it isn't. 'Gaol' is barely used in British english outside of affecting an olde-worlde charm for tourists. British usage tends to words like 'prison', 'custody', 'cells', 'remand', 'detention'... barely even use the word 'jail', let alone an archaic spelling of it (and the pretrial/postconviction jail vs. prison distinction common the US system doesn't apply to the terms in the UK). HM Prison Reading might have a sign outside noting that it is the eponymous "Reading Gaol" that Oscar Wilde wrote about, but nobody's calling it that outside of a guidebook.

I think you’re conflating P(Is British|Uses “gaol”) with P(Uses “gaol”|Is British), the latter of which I would expect to be much higher than the former.

(Oh, and to put you out of your misery, a more recent comment by OP contains the clue: "Where I live (Aotearoa)", which suggests they're a New Zealander. So, you missed your guess by around 11,000 miles, and apparently 80 years or so in terms of English language usage.)

Slow golf clap from me I guess. Pedantry is super impressive.
