I don't suppose this is too bad on the large scale of road problems and incidents, but how many of us abuse a mini roundabout at times?
They have been put in as a "roundabout" after all and should be treated like one as much as possible, depending on its size and location and also depending on the size of vehicle you are driving around, over or through it with. So rather than completely ignoring it as a road inconvenience, give it a go and try to use it - it might even turn out fun!
This 'driver' decided to cut across me from the left hand land (straight on only) to the right hand land (right turn only) causing me to swerve and brake sharply. Thankfully, I am a competent driver unlike this individual. Avoid this vehicle at all costs, who knows what he might do next!
Crossed to cut me up while speeding while I was doing the legal 30 - ahead of a red light! - and with no signal... Changed lanes, no signal, took the left lane at a two lane roundabout (no signal) then turned right - you guessed it, no signal!!
Very good driver
