It only takes one to end your life and all you have to do is read Facebook or Twitter comments to see how many harbour a deep fantasy to murder cyclists. Phil Gaimon has done videos describing his experiences, too. If you’d like to experience the difference in person, ride a bike in the U.K. with and without cameras. You’ll see how a marked difference in the space drivers give you. Pick a region with decent enforcement like London or the north east.

I don’t have the inclination to look but I’d put good money on statistics showing a negative correlation between enforcement of driving offences against cyclists and cyclist deaths or injuries.
