I know exactly how you feel, and it's no fun having to worry about getting run over by someone who is in a hurry and not paying attention, which with most everyone owning a cell phone, your chances of getting run over are pretty high.
Usually Sunday mornings is the best time for me to take to the roads, but after around 10:00 a.m. the traffic begins to pick up. I'm thankful that I have several bike trails that I can ride 7 days a week, and I don't have to deal with the traffic or I wouldn't be able to ride either.
