Yes, it is scary. I get shouted at by people in cars, mostly when I commute at night. Driver and passenger were out of order towards Matt, no doubt here.
Nevertheless I sense a "want to be like the big London boys, show them cyclist have a right to be on the road".
It seems Jaz now has also armed himself with a cam!
Well, boys, we do not live in London and you do not have the experience of the London cam-cyclists.
Matt and Jaz, when there is only a few cyclist about in town, it is easy for somebody, their friends or family to get you back for an alleged slight on the roads. It could lead to

Matt, didn't recently family of a truck driver you uploaded a video of track you to cycle chat?
You say you don't tell your parents half of what happens on the bike, or they would stop you cycling. So you do realize you are pushing it a wee bit at times

(not in this instance, of course)
The bottom line of my post is, I guess, caution out there!
@BentMickey : you and the London you tube uploaders are a role model for the young ones on this forum: stress about safety before confrontation ... please?
