JoeG:
If you had good sight of the tanker, did you not compute the speed at which it was coming to the round about, it not slowing down, and it carrying on going before? I would have, and would have slowed down before.
My next question for you Magnatom, is which way were you going at the round about. If you were going straight on, why were you in what looks like the right lane? A few people have commented on this. From what i saw i thought you made a right at the round about. You went straight on.
Can you comment on that please? I dont think you have done.
Now, Magnatom, your not going to come on here, start a fuss and get another driver sacked are you? 
Before I answer your questions Joe, I should point out to everyone else on here that Joe, for some reason took a dislike to me on another cycling forum. He was generally quite abusive and as a result I decided to put him on that forums ignore list (it meant I didn’t have to read his abuse). I know I was not the only forum member to have problems with Joe…
You point out what you would have done. Well done for your excellent anticipation and riding skills…of course you weren’t there and any guess at what you would and wouldn’t have done is that, just a guess. I had good reason to assume that the tanker was going to stop. It didn’t. I misjudged, however, I had good reason for this.
I was going straight on (third exit on this 5 exit roundabout). If you can point out where the lanes are on the roundabout, I will happily tell you which lane I took (hint it is a single lane roundabout).
As for getting a driver sacked. You are, as always completely misinformed. I have never had a driver sacked. This was a lie that was spread by a bus driver who took a particular dislike to cyclists and myself in particular. I confirmed that no driver was sacked by contacting the company in question (First Buses). First actually were pleased that I pointed out some bad driving by one of their drivers (who had a warning only) and as a result the company took part in a ‘Give Cylists Room’ campaign with me.
I love the first bit.
My dislike was taken to you and others in your little clique(you think theres not one? Ive spoken to new members on other forums and their opinions have been the same of the forum, but you and your chums wont appreciate that will you?). It came along with you and your over reacting, and ‘love’ of cycle craft book.
Oh, i also dislike your high pitched voice when you scream at car drivers.
Now, onto my questions.
You said that you saw the lorry approaching. At what looks like a decent speed. Now personally, i would have looked around the island, then looked at the tanker more. It hadnt yet stopped(i know that just because something has stopped it doesnt mean it wont go but…) so could have easily had a driver not paying attention, not seen the round about, been drunk etc. By taking it that you have made eye contact, its going to stop is quite a mis judgement. Dont you think? Have you never had someone make eye contact with you, but just go anyway?
Now, as for the round about being from a single carriageway, so it only has one lane. I can name a few round about that come from a single carigeway, but it just turns into a 2 lane round about.
Lowdham Island, where the A612 crosses the A6097), is a good example and one which i go through pretty much every day. The A612 is a single carriageway. The road is perfectly wide, and so is the lanes around the round about. This makes it have 2 lanes. The inside one for going right and straight on(although going straight on turns back into a single carriageway but you can just about filter in in time normally) and the outside one for going left or straight on.
There are NO markings on the road. Drivers just use common seance and it splits open.
The A611 that bypasses Hucknall is another one. It has at least one island where the single carriageway turns into a round about with two lanes. Same theory as above. You naturally pick which side of the road in which you need to be on(usually using the right hand side for going right)
There was no need to give me the hint. There are no road markings for two lanes on the round abouts i mentioned. I can give you a link to them for you to view aswell, if you dont think i am right? It shows clearly two cars, side by side, with no lane marking in between, using common seance.
Your right i wasnt there, but all im saying is you could have easily made that 20cm much bigger. Dont you think?
And no, im not always misinformed.

Edit: And Magntom, one of the things i was taught when i learnt to drive was that if something happens, on the road, then you should analyse what you did, how you could of stopped the situation or been safer, handled it better, and learn from it.
Sorry if i appear to be wrong on this.
