But, I hear you say, I am a weekend cyclist, an just want to ride around exploring my local environs. Well, my little chum, you are catered for too, possibly the most.

The white sign near the give way sign is typical of the mapping provided. It gives cyclists an overview of the area, and to navigate you just pick waypoint numbers for that area and follow them to do your route, ie 45, 47, 51, 53, 56, 28, 25, 17. Each way point is clearly marked, and you even get countdown warnings that a waypoint is close. Add to that the national signage for long-distance routes, and local (commuter) routes, and you have a fully integrated cycle infrastructure.
I used a mix of all 3, national ones, so I knew I was going in roughly the right direction, commuter ones, so I knew about local towns off the route so I could detour for food/water/massage (ahem) and the waypoint ones for quick navigation of multiple turns, such as in a forest of national park where lots of cycle tracks merge. These are mainly signed in the way of 'mushrooms' - small metal posts in the ground with waypoint number and directions/km painted on. Keep an eye out though, they're easy to miss if you day dream.
To get through an area quickly, I would stop at a sign when I entered a new area, see where my route wanted to go, then note down the sequence of waypoint numbers, and off I'd go.
