I've had many, many positive experiences with cars/trucks here in NJ. Very few have been intentional jerks. Ohio - really, really nice or really, really jerks. I'm always waving acknowledgements of "Thanks" to motor vehicles here in NJ.

Riding outside of Princeton on a two lane county road, I hear a "toot, toot" back behind me, and immediately I know it's a semi, letting me know that he was going to be passing me. He did it far enough back that it didn't startle me and gave me enough time to brace for any wind blast. Very cool.

Most drivers in suburban/rural NJ are courteous. But soccer moms on cell phones - very dangerous.
