Date: Mon, 25 Sep 1995 20:18:37 -0400 The artificially low speed limits have an effect of allowing the authorities to raise revenue at will, due to the fact that there will be virtually no motorists that are truly following the posted limits at all times. The effective speed limit is really 10 mph over the posted limits, with the police generally leaving traffic traveling at 10 over to go about their business. If the limits were raised, making it more difficult for the police to make traffic stops at will, revenue for the localities would decrease, so official support for speed limit changes would tend to be less likely. Incidences of overzealous speed enforcement on otherwise law abiding motorists generally give a lowered opinion of police in general, as the majority of the public will have few encounters with them in other than those situations. Enforcing speed limits without factoring in true risk factors dim public view of the benefits of having police on the road. Drivers that weave around traffic, cutting off other motorists, and endanger others all too often go about their way unchallenged, while the "speeders" on open roads in good road conditions will be selected for a stop, mainly due to the preferred method of sitting hidden on the road instead of driving around, watching for truly dangerous drivers. It's unlikely that cherry picking will be eliminated, when the rich source of revenue is so easily available.
