Part of the wireless community will be more wizard-of-oz behind the scenes wireless technology development. For example, there could be location specific zones - either implemented via location based telemetry, or, through some form of ISM band technology, that would broadcast dynamic speed limits based upon traffic conditions. Many accidents occur because traffic conditions are changing so dynamically that drivers are caught unaware. For fixed speed limit area - like neighborhoods - the 25 mph limit could be sent as a reminder to drivers, in their cocoon, who's "in-vehicle" brain may still be back aggressively on the freeway instead of their neighborhood or a school zone. A reminder - sent in a child’s voice when they are 25% over the limit - could eventually change their speeding habits in people-oriented zones.
