I was on cruise control on the M4 yesterday doing 75, steadily overtaking a woman in a Safira who was doing around 65-70. There was nothing behind us, and as I was only going 5 mile an hour or so faster, it wasn't the quickest overtake.
I was probably 3/4 or more past her, when she suddenly accelerated and undertook me !!!! , glared at me and gave me the finger
not particulalry bad considering nothing else on the road, just typically impatient and/or stupid
