It’s equally possibly to fail for going too fast while still under the speed limit.

What you’re supposed to do is drive at a speed that gives you chance to react to dangers given your visibility and road surface conditions.

For country roads, they’re typically winding rather than straight. So more often than not, that means you shouldn’t be travelling much past 30mph.

But you are right that straight stretches do exist. They’re just not as common on such roads.

Indeed, I always think of my instructor's words "can you stop within the distance you can see". As that distance decreases, you should be slowing down; potentially there's a cyclist or horse right around the corner.

		There’s an old guy that walks round the small country lanes at rush hour where I live. He wears a hi vis jacket but that doesn’t do much when you have trees and hedges blocking visibility. I’m constantly amazed that some idiot hasn’t hit him.
