Roundabouts are a lot more free flowing than traffic lights. A traffic light will stop you, even if there's no traffic you need to stop for. At a roundabout, you just keep going.Roundabouts cause traffic tail backs as do traffic lights. I've done that journey a quite a few times and each time I have been stuck in a tail back at more than one RA.
Anyway, we can agree to disagree and get back on topic if you like.
No idea, I have a flat here so I've never needed one.So - are there any cheap B and Bs in MK?
