Absolutely. The legal speed limit is 60 in the country - on any road not marked with a lower speed limit. This means that legally, you can drive at 60mph down a twisty single track road with 1.5m earth and rock banks topped with hedges.

You would be an irresponsible nutter with a death wish to try through! And if you crashed, "I was driving at / under the speed limit" wouldn't wash - you would be charged with Driving without Due Care and Attention, or Dangerous Driving depending on the consequences of the crash.

Driving too fast for the conditions (but within the limit) would usually be considered Driving without Due Care and Attention even if you don't crash (although the likelihood of anyone being around to enforce it on a deserted country road is pretty low).

That's not the purpose of that law. That's just the pretext they use to get the useful idiots to endorse it. The purpose of that laws is if you do something stupid but below the speed limit and not violating any other specific laws they've got something to nab you for.
