@Becky and the others advocating cycling TOWARDS traffic, the reason that is a bad idea is that if the car cannot change lanes to pass safely, they cannot slow down enough to not pass you. This would guarantee a too close passing of car and bicycle, not a good outcome for driver or rider. On the other hand if you are traveling in the same direction, the car can at least slow down to your speed until it is safe to pass.
