David, having now watched the video, it is my view that ;
1. UK drivers should not be encouraged to do anything that would permit the viewing of video whilst driving. It is illegal.
2. Passengers should not travel in the vehicle with their feet off the floor and strapped in by a seatbelt. Death comes to mind and it is probably mentioned in the Handbook too.
The concept of using Youtube is highly relevant however, should Members wish to avail themselves in conjunction with the H...B..k !
