I hear you! I watched a car trying to pass a tractor trailer in a traffic circle in Latham, NY. It ended up underneath the center of the trailer! (It's roof was just about completely torn off.) Was that driver surprised, embarrassed, and a lot of other things!
I hate traffic circles myself. And now the state wants to install some more. Even though the people using them hate them, the pencil pushers sitting at their computer screens and running their software programs say "they're safer than the old intersections." Well, if people didn't try to run stop signs, learned exactly what "yield" means, and weren't in such a rush all the time, then there wouldn't be accidents at intersections. Maybe they should do away with "no fault" and prosecute those people that are causing the accidents - like they used to do. Then most will think twice about the way they drive.
