Any downhill section with driveways or intersections. I got hit on 99W in Tigard (20-25mph) when a driver stuck in stop and go traffic decided at the last moment that he wanted a taco. He got a taco alright... my $230.00 hand-built front wheel, my frame, my forks... I have been told that there was $11K in damages to the front (passenger side) fender. This doesn't include my bike, or my injuries. I'm almost done with the Chiropractor, then it's settlement or court.
