That's one of the most "cookie cutter" responses I have ever seen. That's just pure silly. Of course I don't think so. Damn. But I also know restraint can go a long way. I'm amazed you asked that, and from a fellow bicyclist.
Yes, I have been chased, but not far. And you are correct, it was scary, but I got out of the situation before the driver could actually become dangerous to ANYONE. I know how to keep a situation from escalating. When it starts, take a left on a one way street coming at you. Duh. Or a right or where ever the driver/cager can't go. He'll cool off in a minute and then the next person he comes upon whom he feels entitled to threaten may not get the thrashing he intended for you. Think for a minute, the guy harasses you, you flip him off or whatever it takes to make him boil, then you evade him. Now you've turned an idiot into a raving foaming idiot, prepared to release his rage on anyone else he comes upon after you lose him. Does that really sound like a safe way to diffuse a situation? I think not.
I wouldn't have let it go as far as the OP did, had it been me. It isn't worth the hassle, and who doesn't enjoy a little evasive biking. Just think of it as single track.
But then, I'm me, not you. If you feel comfortable fighting the driver for the "last word," go for it. It's way too much work for me, and I generally try to stay happy on a ride. Shiite happens, which is why I gave up pavement for mud 20+ years ago. I did my time on the curb lane and don't have a desire to reprise that era in my life. I've seen more than most would care to. I started at 12 yo with a paper route. I've been hit three times, suffered a broken left leg in one accident and had to take a year off to heal. Any other questions, or can you now get on with your day?
Oddly, I hope your complaint works for you, but vigilanteism is a hard road to go.
