This genius nearly rear ended my works van while flying up behind me trying to undertake a line of cars at speed. I see behaviour like this so often these days, some scrubber picks up a 10+ year old Audi or BMW on its last legs and thinks they own the road. At least karma's already got you driving that poverty spec chavkart as punishment so there's some justice in the world after all.
Overtook on a single carriageway a short distance from the junction and ended up blocking the roundabout trying to leave at the second exit (for what was a long queue for the roadworks 3/4 of a mile ahead).
Thankfully anyone with more preparation knew to take the first or third exits.
