a year 5 (c10yrs) pupil is doing level 2 junctions - turning right from a wide but mellow major road to a minor road.
The pupil has looked back, signalled, checked back, moved across the lane towards the centre with bang on positioning. Signalled again. About to make the turn. Plenty of room for a car to undertake.
So this woman in a car arrives behind the small child in fluoro tabard on bicycle by middle of road. The child starts to turn,..... and the driver moves to overtake!
The child does a lifesaver look back and stops. Meanwhile I, the instructor, am making like a traffic policeman (remember them?) stepping forward holding up my hand at the driver. The driver stops. The cyclist completes the turn.
I walk to the driver's window and gesture for her to wind down the window. She just looks at me. I gesture at the back of my vest with Instructor in big letters and City of Westminster in smaller letters.
She drives off
BITCH
(the class know the value of the lifesaver look though!)
