Having just come back from visiting the in-laws in Gloucestershire (American raised on American roads), it took me a minute to comprehend the national speed limit rule. Nonetheless, I don’t think the rule matters much.

What matters more is the far stricter driver licensing and “Scarlet L” (my words) that the learners have to display.

That and the fact that it is bloody impossible to conduct 2 way traffic down country roads thanks to all the hedgerows and so everyone is extra careful and courteous (usually).
