[SDCBC] Door Zone Bike Lane, was Re: Well it looks like I am not the only one...

[Jim Baross]

You might refer them to the crash experiences in San Francisco. 
Apparently the leading cause of bike into car crashes has been 
Dooring; riding too close to a parked vehicle from which someone 
illegally opens the door into the path of the cyclist. There have 
been several deaths from this.

Seems to me that a properly written notice of hazard (maybe drafted 
by a friendly attorney - hint, hint) to the City of Santee would 
encourage them to move the door zone bike lane away from parked cars, 
drop the lane line and add Sharrows, or some other treatment.
