On fire
Drivers who, in a slow moving queue of traffic leaving a roundabout, insist on leaving a 75 yard gap between themselves and the slow moving car in front of them. This just causes the tailback to extend backwards to the roundabout - causing quite unnecessary queues to build up on ALL of the approach roads to that roundabout and frustrate motorists who would otherwise be able to get through without being slowed up at all.
