It's very important to remember that the cars that try to make hood ornaments of us are (generally) driven by agressive and cranky men and we're women on light-weight bicycles. Some jerk in an SUV practically takes my left arm off and I find myself yelling invective as he speeds away. Irritates the hell out of me but I try to remind myself that I'm a 100lb woman on a 18lb bike and I'm just never going to win that argument. First order of business: keep yourself safe.
