Raise the limit? Where did I say that? Don't change the law, it's perfect. Prima Facie is a reasonable way of writing the law, but the interpretation varies wildly between LEO's (and unfortunately judges I've talked to). By legal definition going above the posted speed is prima facie (assumed or at first glance) to be illegal based on that roads condition. Higher speeds are allowed for if they are "reasonable" and allow you safe distance to stop or maneuver if needed. It's a tax with lipstick on it. Now whaddya got JRMii(i)?
