Sadly a typical response from a Beemer driver - enough there to at least warrant a chat from the boys in blue i'd have thought - hopefully more. At the very least careless driving. Good luck.
What's with all the arm waving? It's not upto you to dictate when vehicles can overtake you.
You give the impression that you will let them pass when YOU want them to and then whinge if they pass when you are (once again) riding down the centre of the lane when there is NO NEED to.
A lot of the incidents you get involved in could be easily avoided but that doesn't make good footage does it??
