the problem is the accuracy of the map. For instance, you can follow the direction of google map but the accuracy of your destination is an approximation of the location you have input not the exact location. that is why the drivers call to ask the description or the exact place you are in. if you are having a hard time identifying the place you are at, just ask random strangers( if you are a girl, try asking women especially older woman, or women that have children.... b/c that's the safest choice)
