A little too harsh here on Prius owners, and, lets face it guys, you are bitter about the gas saving they are getting compared to your vehicle. I’d guess Prius drivers are more likely to drive conservatively and have a lower incidence of hitting bicyclists than other cars.
I once rode my bike to MN. I quickly learned my greatest threats were young guys in pickups and old ladies in Buicks. The first group had it in for me; the second never saw me.
