Hi Victor
I completely agree with you about GPS innacuracy but I think that same kind of problem can happen during the guided driving too.
I am not quite sure if there is a way to get accuracy value from GPS and show some warning if it is more than 10-20 meters?
Also it is absolutely not necessary to apply any algorithm to determine the exact location - it can be just assumed by best GPS signal and warn if inaccutacy is more than some value which can be configurable so anyone can choose as they wish.
