The last three were Honda Accord, Chevy 1500, and a Nissan Altima. All three honked at me as they passed without giving me any breathing room. The Altima was exceptional - this guy accelerated right next to me and honked right as he was passing. I had just one run-in with a BMW driver, who just appeared to be completely oblivious to my presence, a Maserati driver, who was pretty much the same, and once was yelled at by a Prius driver (go figure that one out).
So I guess the moral of this story is that everyone can be a prick.
