This was my downfall. I stopped at a four-way stop, unclipped my shoe from the pedal, and let the vehicle with the right of way proceed. When it was my turn I went in front of a car approaching the stop sign. This car completed what is called a California stop, rolling right through and hitting the gas without stopping, resulting in the plastic of her bumper meeting my skin. It was her fault, but cyclists always have to be on defense—in an accident such as this one, the cyclist never wins.
