This morning's commute was a bit like something out of the film Duel. When I joined the ring road, a lorry flashed its headlights to let me on. We both left at the same junction and drove 3 miles down the same road, turning right at the crossroads.

I pulled into the car park to let Emma out, then turned around and drove back to the main road. The lorry had also pulled into the car park and turned around, and followed me back to the road.

At the next crossroads I turned left, with the lorry following me. I took the next turning left, but by now I had managed to get a bit ahead. I think the lorry also took the same turning but it was too far behind me so I can't be certain.

I'm sure this is just coincidence, and nothing sinister at all. There are roadworks in the area and some roads are closed. Otherwise the lorry wouldn't have had to turn around where it did. I think the driver might have found himself at the wrong end of the roadworks and the route to the other side happened to be the same route I was taking.
