I go to work at 5:30 in the morning. I have on several occasions narrowly missed idiots riding their bikes on the road. Aggravates the sh!t out of me. I wouldn't "hit-and-run" but that wouldn't make them any less dead.
Actually, it’s safer to ride in the morning than in the middle of the day. 2AM=no traffic. I used to have a job that made me work early in the morning and I went to work on my road bike and didn’t come home until 9AM. The ride home was a doozy because everybody was going to work, but the ride to work was smooth sailing since everybody was asleep.
