Nice one Mike.
I disagree a little with the head mounting being more shakey. This was the case with the ATC-2000 which seemed prone to wobble, but the new camera I have seems to provide more stable footage even attached to my head.
The other advantage of having it on your head is that you can analyse your observation skills, i.e. it allows you to see when you are looking and where. This could be vital evidence in the situation of an accident.
It might be worth including some evidence for your power of one section. Not wanting to blow my own trumpet but my experience with First proves that having video evidence can make a difference. You could link to the Evening Times article.
Actually I am going to meet with Glasgow City council over the next couple of weeks to chat about how they can help to take things further. Very positive!
Lastly, how about a link to actioncameras
http://www.actioncameras.co.uk
They aren't the cheapest, but they do have plenty of examples on their website of different cameras and set ups.
