In Britain, the speed limit has never been that low. All dual
carriageways ('divided highways') have a default speed limit of 70mph.

Britain didn't have a speed limit until 1967 when the 70mph
national limit was brought in. The "unofficial" speed limit on British
motorways is 85mph. 90-100mph is common. Turbo-diesels are
ideal for these sort of motorway speeds. Good torque for overtaking
and pretty frugal in the process.

Anyone who comes here from the US or Canada complains that
we drive too fast.
