I recently ran into a report where user reported a general error due to inaccurate GPS positions. The GPS drive segment had them well off the route while traveling south on a highway. It eventually merged back onto the highway but it took about 1/2-1 mile to correct itself. When I looked at all the GPS position reports in the area, the north bound traffic was heavy with yellow indicators and were dispersed in the south bound lanes and also off the highway. The south bound side had dark blue or black indicators, I did not find a single green indicator within that 1/2-1 mile.

My question is, would it be prudent to have a tool that marks a certain area as having a high degree of GPS error? Could that be linked in with the app, so that the app could assume that travel is being conducted along the route until the GPS signal accuracy returns?
