Why the war-

Just yesterday, I was on my way home from a doctors' appointment. At one point while I was 'taking the lane' and a motorist in an SUV gave me enough room when passing. When he proceeded back into the lane I was in, he suddenly started rubbing the edge of the raised sidewalk(parallel to the road) with his SUV. I thought he was going to rollover. Some people may chalk that up to coincidence. I see it as an indirect example of his hostility towards cyclists. By rubbing the edge of the raised sidewalk with his vehicle, after he had passed me.
