I was just down in embarcadero picking something up. In my 10 minutes while searching for the frig'n freeway, which I can never find because SF's streets are moronic. 3 times cyclist darted out, right in front of cars, not with lights or clearance in their favor, in front of me. Just went in front of us and we had to slam our brakes. Only one instance a cyclist was in his bike lane, and some white old phart driving a red corvette musta held his horn down for a good minute long at him for going so slow. Sometimes, I wonder if cyclists are a bit more responsible for what comes upon them.
