“How lovely to be home” I thought as I rode along a narrow one way street with the traffic.
“Brrrmmm, Brrrrm” Said the car behind.
“Funny, why are they doing that?” I thought. “They can’t be trying to overtake because there isn’t any space, and anyway, I’m riding as fast as the vehicle ten metres in front”
“Brrrmmm Brrrrrmmmmm” Said the car behind.
“I guess there’s something wrong with the clutch, or something” I decided.
“Brrmmmm Brrmmmmmmmm, Beeeeeep” said the car behind. It was almost alongside me now, somehow squeezing into a gap between the parked cars. The driver was waving at me, which was nice.
I waved back.*
The driver noticed they were about to drive into a parked car and stopped suddenly.
At the end of the one way system we entered a wider road and the white van pulled off. Car behind pulled past. The driver waved quite a lot this time.
I waved back again.
The driver seemed to be happy to stay with me and drove  v e r y s l o w l y  in front of me for several metres before pulling off and stopping at a house.
I would have stopped to further our aquaintance but I had an appointment to get to.

* Because they couldn’t have possibly been trying to push me to the side of the road to get past as this is a highly illegal and dangerous manoeuvre, which would only have enabled them to get a few metres further.
