Had a low speed "buzz" on my ride today and I went ballistic. I ride on a peninsula in So Cal that is in a land slide area and the road is under regular repair. The road crew was out paving today causing intermittent lane closures with traffic stopped to share what became a single lane road - however the bike lane was clear. In one stretch as I went by stopped traffic (me in the bike lane) there was an older guy (hey I'm an older guy) who looked at me and swerved into the bike lane as if to stop me. I may have been going 10-15 mph (max) and he was crawling when he swerved while clearly looking at me. Sigh.. I narrowly missed his mirror and of course screamed at him while passing on his right. The road crew waived traffic on, he caught up with me, slowed and for a moment we're going the same speed and he is is giving me the "stink eye" and yelling at me (well his lips were moving). Now I'm screaming back at the guy to pull over because I seriously wanted to pound him. He snarled at me, looked like he may, but then drove away. There is no doubt in my mind he intentionally wanted to stop my progress when I passed on his right (while I'm in the bike lane). He was a reasonable looking guy in a nice car, it was weird... Was he a cycling hater who was mad at being delayed? Perhaps... The rage it brought out in me was scary and after I calmed down I wondered why I was so ready to hurt this guy. Adrenalin, fear of death? Don't know but I'm glad he didn't pull over as I may be writing this from the local jail.
