I agree. Excessive acceleration in a school zone... busting the legal speed limit...
Red's comment "Too much chance for abuse for me" is right on. Maybe knowing that an EDRS is in a vehicle might keep a driver/rider from killing more kids... or themselves.
We must always keep in mind that we do not have a "right" to operate vehicles on public property. We are granted a license to operate on public property subject to certain requirements several of which are obeying laws.
Way I look at it, if you crash doing 65 in a 55 zone, and the insurance company can show via the EDRS that that is a fact, your claim should be denied as you were breaking the law at the time of the crash - criminal activity is usually not covered by most policies.
Bring 'em on!
