The next video shows a white van advertising 'SECOM', reg no: KY65 NCU, and as I go by, it appears from a side road, and keeps my car company, so to speak, for a good few minutes, and then it reappears and is slightly ahead of me for another period of time.

The video also features footage of the driver taken from a camcorder mounted on the passenger side window.

Note also — a transit advertising a company called 'ACE'.
