Strava pulls in position and speed data so accurately that it can often be used to identify what lane a cyclist is using on a particular road. With such accuracy, could the government use Strava data to figure out if a cyclist ran a stop sign or a stoplight? Could it be used in the event of an accident involving a vehicle to map a cyclist's behavior prior to a collision? This is just speculation, as the data is intended to be anonymous.
It would be easy for them to create a database of Strava's user-created "segments" to identify "hot spots" where cyclists may be riding in especially aggressive fashion. In his piece in Bicycling magazine on the Strava-related death of Kim Flint in 2010, David Darlington compared some of the site's "KOM" segments to illegal street racing. He even showed how easy it is to identify cyclists breaking the law by finding several KOM segment leaders who recorded speeds in excess of the posted speed limit.
