We tragically experienced the same thing — 2 fatalities and 1 severe injury within a 1-year time frame — on State Route 1/Mission Street a few years back. No bike lanes, bicyclists riding to the right getting squeezed by freight trucks. But what came out of it is the STATE OF CALIFORNIA installing non-standard signs allowing bikes to use the full lane. (This was prior to the MUTCD adoption of BMUFL). So yes, there is a blessing in all things. Love to all.
