Let's say you wanted to drive from the zip code 10302 to 10308, which are both in Staten Island, New York. If you plugged that into Google Maps, Google would tell you, you have to be prepared for a three hour or more commute.
For some unknown reason, a bug in Google Maps, thinks the zip code 10308, which is owned by Staten Island, is in Schenectady, in upstate New York.
Adam from the Google Maps team confirmed the issue in a Google Maps Help forum thread. He said:
Turns out this bug is an artifact of a known issue we're working to resolve, so if you haven't reported this yet to Tele Atlas please don't expend the effort.
So, if you are driving to 10308, be careful when using Google Maps.
