A scanner in your car will be of little or no use to avoid speed traps.

a. Many, if not most, states have laws forbidding the installation of
"radios capable of receiving police transmissions" (or similar wording)
in any vehicle not designated as "official" or "emergency".

b. The kinds of info transmitted by state and/or municipal police are not 
useful for determining the location of radar speed traps or other speed-
checking methods. You'll be constantly "false-alarmed" by drivers' license
checks and suchlike radio traffic, and anything interesting is referred to
in cryptic codes (which can be learned, of course, but are seldom worth
the effort -- plus, they change from region to region).

For more scanner info and discussion see net.ham-radio; if you have access to
archives of that, there is much to be gleaned therefrom.
