In order:
- more locations closer to home to use instead of the streets
- if the person is actually doing something wrong, pull them over. Don't pull somebody over just because they have an exhaust, and pretend its a 'random' test.
- no, they need to make it cheaper/worth our time to do so. this is also covered by the first point, because if the tracks were closer they wouldn't have to drop their price by so much as we would be saving in fuel/food/time.
- cruising is fun. Never to see how many people we can drag off the lights, or how fast we can get to a location. Having a nice car and showing it off as you drive along is one thing, doing a burnout and going sideways up a main street is another.
