Always always always go in the direction of traffic. Today I tagged along in a car with a friend. We continued slowly on a one-way street and the light was green, so we kept going. WELL...unfortunately a cyclist came at us approaching the driver's side, and he was riding the wrong way of a one-way street.
Obviously b/c of this, he was unable to see that we had a green light, and he would have had a red light had he been going the right way. We did our best to swerve, but he still clipped the back of the car.
Both he and his bike seemed okay (save for limping on his ankle), he was sheepish, probably realizing how in the wrong he was. I was just glad everyone was okay, I mean, what would have happened had he blew the light when we were already in the intersection? He would have smashed into the side of the car, possibly hurting himself more. OR we would have hit him head-on.

So, just a friendly yet firm reminder to all us who occasionally go against traffice to please take a different route.
