Fortunately I live in an area where I have great choice of relatively low volume, low speed streets from which to choose and rarely have issues. Every once in awhile just have to get out on major thoroughway to reach a destination and I think about those things from the second I enter that road to the second I get off. I've been agressively streered off the road once. I think about all the people I know that have been rear ended at least once in their vehicles, no reason that can't happen to me on my bike. Must always be alert in traffic.
