"We're making a statement tonight," she said. "We believe in sharing and being nice."

Dagasan is the founder of Critical Manners, which is her response to the controversial Critical Mass ride that features hundreds of cyclists riding as a pack through San Francisco on the last Friday night of the month. At the last Critical Mass, there were several confrontations with motorists, including one that ended with someone smashing the back window of a minivan.

There was none of that for the Critical Manners ride. That's because Dagasan put her foot down. She put her foot down at Grove, McAllister, Turk, Sutter, Bush and California streets, and that was just during the first half mile. A law-abiding bike rider puts her foot down a lot.

The ride departed at 6 p.m. from Civic Center, after a brief refresher course.

"Let's review our signals!" Dagasan hollered to the group. "Right turn, arm up! Left turn, arm straight out! Now put your helmets on! And be polite!"
