It has been a while since I have had any issues. I believe drivers on my route are used to me now. Plus, taking the lane more often and expecting every motorist to attempt to hit me helped.
That said, almost all of my 19 mile route is in low traffic areas.

Ah! Thought of one. Last week a driver in a bmw buzzed me. However, he was traveling 1/2 the speed limit and slightly faster than I. Plus, I had not taken the lane yet (narrow street with parked cars).
