Sorry Glenn, can't agree.
Yeah, its irritating when someone overtakes you, then is almost immediately stopped by traffic....but, that driver quite probably commited to overtaking you, quite reasonably in my view, when the road ahead of you allowed it at the moment the decision was made. That decision was made before you even saw her. Circumstances then changed...so what, it happens to us all, drivers to drivers, cyclists to cyclists, cars to cyclists, its a set of ever changing circumstances, no one can predict everything that'll happen.
Irritating, maybe....bad driving ?...not IMO.
