Just coming home with the mrs and son from school, got to a roundabout where usually people never get in the right lane the exit is past twelve o'clock so you get in the right hand lane. Not as a bloke in a Skoda roomster has just done and was literally about an inch from the rear of my car, he then had the damn right cheek to toot at me! Then waving his arms around, then there was some nice verbal abuse from me then he kept going so I stopped in the road, and said to him in not such a polite manner, read the highway code, don't toot at me when you're in the wrong and if you want to carry this on get out of your car, he quickly then shut up, then turned down another road
I wouldn't have minded but trying to imply I was in the wrong really got my back up. What is it people can't grasp if a turning on a roundabout is past twelve o'clock USE THE RIGHT HAND LANE. I was already in a bad mood today and this pissed me off even more.
Rant over, hows eveyone else's day been?
Is that the TA / Tank roundabout Del? :-/
If it is yes many a time people have tried to do that to me, and I have seen drivers do it to others, with on at least one occasion a car ending up on the grass verge!
When I had my old Toyota I just used to indicate and turn left as you should, with anyone trying to come up wrongly on the inside having to give way or risk denting their lovely polished car.
With the miggies I am a little more careful and just use my car's power and my experience to slot in.
That roundabout, and a few others around, really require road markings to remind those forgetting about the Highway Code where they should go!

EDIT: I have just seen your Google map reference, and yes it is
that roundabout!!!
