well, beyond what's around you, I STARE at people. I notice what they are doing and then make a list that goes something like this:
red sebring, guy depressed with head resting on arm.
brown camry, putting on makeup
blue concord, on cellphone
grey integra, bass system
black minivan, kids inside
And then I plan everything that happens from that moment on and do whatever I can to avoid them. And I will STARE at them and identify, and then keep checking.
On the bike now though, I'll tap on people's glass to make an effort of keeping my ride trouble free (*tap**tap* "Excuse, are you always that fucking stupid ? Hang up the fucking phone and drive, moron. And if you come near I'll shank you")(Exagerated)
But yesterday I had this cunt pull out in front of me, then I squeezed by and honked. And they honked their horn BACK AT ME. At the next stop, I went to the side, pushed the bike back to their door and let into them about how much of an asshole I felt they were. My other friends usually punch their mirrors off.
