I think i've got those calculations right - basically a circle and a quarter.
My usual roundabout home from work has been extremely busy all week because of road works and diversions nearby . Two lane roundabout with 4 exits.
I normally take the first exit, and have been sitting in the left lane for up to twenty minutes each evening because of a big queue of traffic all the way up the street towards the roundabout. Right lane maybe has the odd few cars in it - 3rd exit only leads to a small car park for some shops.
So yesterday i just went right into the right lane, did a full circle round and then left at my usual 1st exit. Only three cars were in front of me. I waited less than a minute.
Roadworks are expected to last all next week too. I'm wondering if I can carry on doing this or if I'm technically doing something wrong. If it's perfectly legal - why isn't anybody else doing the same?
