Driving in England

The fabric of the British road system is stitched together by 'roundabouts' and 'bollards.' A roundabout is an intersection, as you can see in the first picture, which is the sign for the Running Horse Roundabout. However, like most major intersections here, the intersection is a traffic circle from which there may be any number of exits, or even connecting roundabouts as you see in the picture. The trick is to enter the roundabout in the appropriate lane so that you are prepared to exit at the right time. This definitely takes some practice and has been the times I have most frequently heard my fellow motorist's "salutes". It seems chaotic at first, but once you get used to it you realize you were right the first time, it is chaotic.
Bollards are essentially permanent traffic cones. The word 'bollard' is pronounced like our southern delicacy "collards", but probably tastes better. As a friend of mine here in the UK describes them, they are "primarily here to dent and scratch your car. " They have lights inside them, so you can see them at night. The traffic configuration in the picture is very interesting, and very common. I can only imagine it's intent similar to US speed bumps, to slow traffic. The bollards narrow the road to one lane and one lane is instructed (as noted in the sign) to yield to the other lane. That too can be a noisy experience when you first get here and don't understand that you are supposed to give way to the cars coming in the other direction. So far I have managed to avoid hitting a bollard. I've hit garage walls, the entry posts on either side of our home's entrance to our parking area, and run over many, many curbs, but have managed to miss the bollards. (but give us time)
I recently had occasion to drive a couple hundred miles north for a work assignment. The highway system is fairly easy to follow. The major roads are "M" (for "motorway") and a number, for example the 'M4' is the highway I take to work every day. Just like the US, the even numbered highways run east and west and the odd numbered highways run north and south. I took the 'M1' most of the way to our Ripon office in northern England . The local inter-city connectors are designated 'A' and a number, for example the 'A329' connects me to the 'M4' every day. Some of those can be multi-lane and highway speed. Lesser roads are designated 'B' or 'C', although I haven't noticed any 'C's yet. They also use a convention of putting a road in parentheses if the road you are on connects to it. You can see an example of that on the Running Horse Roundabout sign. If you take the second exit you are on the 'A329' which connects to the 'M4.'
All in all, just like most things in the UK, they make perfect sense once you understand them.
