the silver BMW was a sensible distance from the car in front - you used to roundabout as a chance to overtake him and pull into the gap he had left...if there had been no overtake chance on the way out you would have been stuck there, forcing to him back off more. I expect the BMW driver thought you were a tool and I'd be staggered if you'd do it to a panda car.

Not bothered what the HC says....if any of us had someone jump us on a roundabout to pull into the gap we had left we'd have been pissed off - the overtake afterwards could not be forseen as a certainty.

That might depend on your definition of advanced driver.

Formal test? Track training? Advanced training? ex police response?

By your definition, non-advanced.
I fail to see how being an advanced (by your definition) driver stops the possibility of the BMW coming out of lane?

I would have dealt with the risk of being driven into by the BMW by not overtaking it on the roundabout, thus removing the risk.

Basic stuff.

I'm really not sure I need to answer that but if I must:

Drivers go straight over roundabouts because it is easy to do so; they don't have to steer as much.
This happens all the time, I see it everyday.

Drivers travelling on a 'normal' piece of road do not veer out of the lane because there is no reason to.
This doesn't happen all the time, I don't see it everyday.

Yes and these same drivers seem to strugle with the concept of mirrors and indicators , my take is it worth the risk of loosing a NCD and the other hassle if you have a little fender bender... for gaining a few minuits ???

I cant see what test (GCSE phsycic maybe?) helps you avoid hitting the bemmer when he straight lines it - or when you fail to get an overtake on the exit what test stops you looking like a tool that just used the roundabout to hop into the bmw's safe gap from the car in front?

Go on then, let us in on your foolproof method.

Alright dear, no need to shout. Is that how you treat your pupils when they question you?

I don't understand how you can say
You can never KNOW. You can have a good idea, or a fairly safe bet, but there is no possible way you can KNOW every time what certain road users will do in a particular situation. I couldn't even guarantee that I would stay in lane if I hit diesel or had to take sharp evasive action, let alone anyone else.

The only thing wrong with any of it is the, temporary, occupation of the BMW's braking distance. The BMW would be absolutely fine to straight-line the roundabout as they would do so behind the OP, the OP being ahead of them before they're even on the roundabout. Who the driver thinks is a "tool" and why is beyond the OP's control and not something they should worry about, especially being as the likelihood is they're wrong.

As for whether the "advanced" driver would believe this to be an OK manoeuvre or not is probably down to whether they're an advanced driver in the sense that they're actually a better driver than most or in the sense that they rigidly apply a set of rules to every situation regardless of how appropriate it may be. I've been reading this forum for a little while now and there seems to be a LOT of the latter whose "advanced" driving must be no better than most of the berks who do 45mph everywhere without paying any attention at all to what they're doing. As somebody else said on another thread, it would be very much a case of "sorry I ran over your child but did you appreciate my lack of brake-gear overlap?", you may be "correct" but you may not be "right".

There, that's bound to elicit an angry response from exactly the people I'm talking about.
