This is just a sad story all around. I feel for the Deputy and the cyclists:
We need to share the road, meaning: give as much room to cyclists as you can without compromising your safety with oncoming traffic. If it looks like you can't pass safely, then please WAIT! until it is clear to pass. Please don't forget that bicyclists are considered to be vehicles on the road, too, and your car is much heavier that they are!
Just think of the CO2 you're saving by riding a bike to work!
UPDATE: the numbers are out from the CA CHP:
As a cyclist, I think these numbers are skewed against us, but I have also seen many unsafe riders.
