Shrewsbury has an inner bypass - one lane each way but fairly wide, with 5 ace r/bouts dotted along it. On the r/bouts the road is 2 lanes wide. I occasionally overtake on the r/bouts, which means cutting in a bit smartish to get the exit. Normally goes OK but about a year ago some old boy got very upset - lots of horn and flashing lights etc, surprising for an old goat really, I didn't know geriatrics knew such things - and just recently, a few weeks back, I upset some chav in a Corsa who chased me down to the next r/bout - traffic light controlled and on red so no escape. I had my earplugs in so didn't hear exactly what he was yelling but the gesticulations of the tattooed hand were enough... Safe? Not safe? Would you overtake on a roundabout?
