I was cycling in a westerly direction in primary position, approaching the junction of Harcourt Ave and Chelmsford Ave, about to execute a right turn followed by a left into North Road. A white Smart/Aygo type car suddenly appeared 6 inches away from my right elbow, also turned rignt and then left, and then stopped. I stopped and tapped on the drivers window. The driver looked up at me and I said "I'd like to talk to you."
She wound the window down.
"Why did you overtake me just then?"
Blank look. "Just when?"
"About 10 seconds ago, as I was about to turn right out of Harcourt Avenue. Didn't you see me?"
Sigh. "Yes, I saw you. I'm sorry. I was preoccupied. There's an awful lot going on in my life at the moment."
"Same for me, and I'd like it to carry on doing just that and not have it cut short by an inattentive motorist. Thank you."
And off I rode, feeling terribly guilty because the poor woman seemed to be about to burst into tears. Five minutes later, after I left my erstwhile destination of the doctors' surgery, I saw her again. I think she had been sitting in her car trying to get a grip for all the time I was there.
