Google Maps is generally very good, but will occasionally give you stupid and/or illegal directions. Examples include u-turns at intersections where it is explicitly or implicitly prohibited; turns onto the wrong way of one-way streets; round-about directions in the vicinity of your destination - where it usually expects to route you right in front of the building no matter how impractical that is; and of course general ignorance of temporary obstructions like construction. I've received all of these bad directions and more.
Many of these things are to be expected if you understand their data sources, and for most drivers who are paying attention to the road more than the GPS, these are non-issues (e.g. drive legally and let it reroute). But, you do have to do more than just purely rely on Google Maps directions.
