I was riding home from work and I couldn't make a left on a road because traffic was bad so I decided to ride up the sidewalk towards traffic and wait for an opening to cut across. There was a sign blocking the walkway a little ways ahead (one of those big orange road work signs) but I thought there was an opening in traffic to cut across. I sped up a bit and started to cut across when I noticed a car speeding towards me in the lane I was about to enter. I got scared and cut my bike back on the path, hit the sign, and flew in a bush. I did have the sense to duck my head so my helmet hit the bush first. I never had the sense to just hit my brakes.
I just laughed.
