Dear inattentive moron in the Ford Taurus,
Please explain to me why for some reason, 40 MPH in a 25 MPH zone and 35 in a 50 MPH zone are both within your normal driving realm. Please pick a relationship to the speed limit and go with it. If I attempt to pass you because you are going 35 in a 50, please do not then decide to speed up to 60 while I am trying to pass. Also, there is no need to ride my bumper when the speed limit slows to 35 again, and I am going 40.
