No because I'm prepared to drive. I consider myself a fairly defensive driver, I use my seatbelt, I obey the traffic laws/speed limits, I don't drive intoxicated, I limit distractions, and my vehicle has a number of safety features that were designed based on generations of testing. I even go so far as to run winter tires during the cold and icy months.
Do you feel safe when you drive? If so, why are you looking into other's cars while driving?
