Approaching a mini roundabout I was towards the middle of the single lane. Apparently I drifted left slightly as I stopped and waited for a car on the roundabout, because an old bloke behind me decided he'd take the gap ahead of me and floored it around me and right in front of the car on the roundabout. Towards an obvious red light about 20 yards away.
I gave him a wtf gesture, he wound his window down and proceeded to berate me for not signalling. I was going straight on! How tf am I supposed to signal straight on?
