Yesterday's aggressive driver was purely that - aggressive. A woman in late middle-age with a heavily made-up face and dyed black hair had been a couple of cars behind me for a few hundred yards. I was cycling along a residential road with cars parked either side so car no. 1 was unable to overtake. Eventually, just after I turned left onto a slightly more major road, driver no. 1 overtook but within 100 yards had to stop at a roundabout. I took primary but driver no. 2 hurled her car into the other lane, oblivious of whatever might have been approaching from the roundabout, but still didn't have enough power to get past me, instead, cutting in and forcing me to the left.
I remained in front and I'm afraid that my PCness left me with the expression "God, you're an aggressive cow, aren't you?"
I pulled out onto the roundabout in front of her, she overtook me on my left, turned into the same exit that I needed (my house is along that road) and promptly joined a queue of about 50 vehicles. My parting shot as I overtook was "Have a nice queue!" and within a minute or so I was home.
None of that was as a result of inattention or laziness. It was pure, calculated aggression borne of a prejudice against cyclists.
