Re: Magic Roundabout
#2If you consider that I'm from the part of the world where everybody is driving on the right side (see what I did there?:) of the road, it was not a complete disaster. Up and close this magic roundabout actually is not so magic - just one large roundabout with few smaller entry/exit roundabouts. Though, first timers could easily drive round and round for a while.

The UK is not exactly alone in driving on the left : Nations like Japan, India and Indonesia keep it company (among the 76 [0])...
One explanation that always made sense to me is that when driving a manual/stick-shift car, taking your dominant hand (statistically the right hand) off the steering wheel for a secondary task like changing gear is more dangerous... YMMV

Yes, I'm informed. This comment was not ment to be insulting to those who drive on the wro.. left side of the road. Just an observation of specific roundabout from a person, who drives on right one each day.

#5This is basically two normal roundabouts, one inside the other, with traffic direction the opposite way in the inner lane. Or a two-lane roundabout. It allows you to spend less time on the roundabout if you want to take the junction to your right, as you would usually have to go to your left and do an almost complete lap.
Compare reaching your parent on a singly-linked list to a doubly-linked list. Being able to traverse in either direction may provide significant performance boosts...

It's actually a lot easier to navigate than it looks, you can essentially treat the whole thing as one giant roundabout by taking the second exit on each mini-roundabout.

Going by the diagram, I think it makes more sense to think of it as 6 roundabouts in a circle. The inner "reverse roundabout" is just you entering and leaving each roundabout by the first exit in turn. The "outer roundabout" is similarly you entering and leaving via the second exit of each roundabout. Neither of those is a true roundabout as you don't have right of way once you're on it.

Also Australia & NZ. Most people forget those two.

Incidentally, most of the traffic comes from Queen's Drive, Drove Road, and Fleming Way (Shrivenham road has been closed to through traffic for many years).
Having ridden across it on a bicycle regularly as a teenager, it works surprisingly well.
