Just a couple of comments on the videos.
The first one was obviously in Scotland on a single track road with passing places. The vehicle from which the video was taken should have pulled in to the passing place on its left to allow the other driver to pass.
(The Highway Code, Section 133, states: " If you see a vehicle coming towards you, or the driver behind wants to overtake, pull into a passing place on your left, or wait opposite a passing place on your right.")
In the second one the driver was using a hand-held video camera; are you really in complete control of your vehicle with one hand out of the sunroof videoing the traffic behind you ?
Let he who is without sin. . .
