Just watched a trailer for "Unhinged" on YouTube. Yikes!
Yep, gona stick with my practice of not honking at, flipping off, yelling at, etc. strangers even if I think I'm right. Just not worth it.
Folks that think that just because they're in their car, they're somehow safe from the wrath of a (rightly or wrongly) offended person must be nuts. Don't honk at or flip off another driver anymore than you would do the same to a big, mean lookin' dude who let his shopping cart bump into yours at Kroger. Assume you'll be face-to-face with the person whether you're standing next to them or in your car behind them.
edit: Just for entertainment, I just Googled "Chicago road rage shootings" and got pages of relatively recent incidents. I'm stickin' with my "no honkin' or flipping off" policy!
