There was an article in the L.A. Times a few months ago where they stated that the number of cyclists killed by motorists had doubled from 2005-2006.
Bad news, but the reason might not be as grim as you think. Apparently the number of bicycles sold also doubled during the same period of time. If there are twice as many of us out there, and everything else stays the same, then the death rate would also double.
There are more and more people riding bikes. Me and my girlfriend even went to a club on our bikes last night.
Drivers, please be careful.
