Rude driver, pulled across a roundabout without looking, responded with a middle finger when he heard the horn warning him of oncoming traffic forced to brake.
Well, you know the score. The arrows painted on the road are only advisory, so merc is not breaking the law and appeared to be moving lanes cautiously. If anything you were poorly positioned, having to jump from the right lane to the left lane to exit. It could even be argued you were cutting the merc up. Have a nice day and drive more safely next time.
Why can't operators of private car parks fine people who deliberately ignore clear signals and drive against traffic? This prat was just the first of three I witnessed in the space of ten minutes who either couldn't read 18 inch high letters spelling No Entry or couldn't see twelve foot long arrows pointing the way they should be going.
The bike clearly pulled into the middle of the road once he saw the car behind. Why ? because they are a bellend.
