Of course there is an important factor in my riding position thats not been stated.
Parked cars to my left, 3 to 4 ft wide cycle lane, traffic to my right. I'm in the door zone normally but usually to the right of the cycle lane. Still in the door zone, but not that close to the parked cars. Usually about 3ft away. That gives you some time to react.
There's riding in the door zone...and there's riding perilously close to parked cars. I dont do that
Still...i prefer to take that infintessimal risk (based on my experiences), rather than ride for mile after mile in the traffic...where 99% of drivers will not understand why i'm there anyway, and you'll get into far more regular problems with the traffic (based on my experiences)
We often have these disagreements. I know my style is not neccessarily the absolutely correct or even one you should encourage, but its my experience, which is as relevent as anyone elses.
52 years old, say 40 years cycling, 12 years or so serious cycling, many thousands of miles covered...not once have i been ever knocked off, had an actual accident or been doored. Although i ride fast I am very observant and therefor must be doing something right.
It'll happen one day perhaps
but i consider the risk of my style to be preferable to the risk of mixing it with traffic any more than i have to. ...which i always enjoy anyway
