Well done Jonny for counting! Is there any error in that or is it a spot on count. Also did you include cars on the side roads, and cars that turned off?

Aye, only one other cyclist. It is a chap that I have met a few times. Turns out he works in another hospital in a radiology dept (as do I!). Nice Van Nic bike as well, not sure if it is Ti or not....
The music was one of the youtube choices, and seemed appropriate, i.e. nice calm music which fairly accurately depicted my state of mind during the filtering, against the backdrop of driver frustration! Ideally I need a piece that would have a strong gentle melody with dark undertones grumbling away in the background. If anyone wants to write such a piece for it....
So the challange is on, film your tailbacks. 612 to beat!
