"The AIDS Walk San Francisco is happening in Golden Gate Park; Please be advised that the area will have increased pedestrian and vehicular traffic during that time. If you're planning on fast park ride, please consult the route map and plan your ride accordingly."
“The fact we cannot say definitively that ticketing cyclists for not making full and complete stops necessarily decreases injuries or otherwise reduces collisions gets to the very heart of the issue: Sanford's impending crackdown is not data-driven...
And all the while, this crackdown will better enable motorists near and far to continue, without consequences, to commit the five traffic violations that the data clearly shows us are causing the greatest harm to the most road users.
Bias, bias, bias.”
