I got an angry honk from a big black truck as I was coming down a big hill on Laketon in Penn Hills last night... I could tell it was angry because it blared for a long time twice before skimming my elbow (I was taking the right half + middle of the lane, I didn't know how fast I was going or what traffic does so I was reluctant to take the whole thing). Thing is, I was moving so fast that s/he had trouble passing me until I slowed down. Then made a left onto a side street and pulled into a driveway. Because I slowed him/her down soooooooooo much.
I try to pity people who are so angry, so unhappy, so miserable that they spend their precious energy displaying that fact at some poor schlup on a bike (me).
And true - at least if they honk you know they see you!
JZ - I agree completely. Or in the summer, when your neighbor insists on coming home at 11:30 during the week, and parks under your open bedroom window (no AC), and uses the keychain to lock their SUV AFTER they go into their house... noise pollution for lazy people. (there's a way to turn off that setting without disabling the panic button)
