Speed limits need to be set to what the police are really going to enforce. What is legal and what you can get away with should be the same thing, especially as self driving vehicles become more common.
IMHO, you have that bass ackward. If a cop is seen in traffic running over the limit, he better explain what is more important he is doing or head for unemployment line.
Of course in many areas tickets are a tax. In my home town, every speed enforcement operation is out on the interstate. Limit 65, traffic moving 60+, tickets normally 75+, but all going the same direction. Most impact is between vehicles with a speed difference of maybe 20 MPH. Now look at the residential areas. Limit 25. At the limit, hit something coming out of cross street, 25 MPH impact. Then add the odds that crossing object might be a kid chasing a ball, 10 MPH over adds more risk. When the chief of police is asked, "It takes longer to spot 1 in light traffic, and cop is always facing the wrong way."
