Yesterday morning heading south on Murray I pass two people sleeping across the railroad tracks in sleeping bags. One has his/her arm over the other in a tender manner that juxtaposes nicely against the scattered bits of trash and newspapers.
Tuesday night by Soquel and Frederick, some douche in a big black SUV with his cell phone up his ass, coming in the opposite direction, makes a left right in front of me. I brake enough in time and he speeds up to get out of my way. I get home and recharge the batteries for my lights.
Saturday morning by Broadway and Ocean, in the bike lane (as usual), no helmet (not as usual), bright beautiful day - white compact on my left slows to turn into driveway, i assume he sees me, he doesn't. I brake and fumble for my bell, i miss the bell, and end up yelling the first thing my brain can come up with: "Whoah, whoah! WHOAH!" He slows down just in time for me to pass - maybe a foot away.
Whomever said separate bike paths (i.e. away from car dominated roads) aren't necessary is clueless.
