So, are you basing that on your one gas station correction?
Taking a look at the entire offering in my area from general use and using it on a regular basis, I would say the opposite...it has improved 1000% since first intrduction. Parsing logic is the best part in my opinion...and I have seen significant improvement in poi additions in my area and rarely have issues during regular use in finding stuff. And recently, for me, it has been better than Google (and more up to date from a street/directions standpoint).
The obvious issues remain as number of and poi's and correctness in some cases as well as the parsing can still be improved...but some of the parsing issues are sometimes directly related to the lack of poi info...
If you keep looking for the one or two same issues it has had since the beginning like your gas station and see it isn't correct, doesn't mean that there aren't 1,000 corrections that have taken place.
I search for everything, even places I know, just to see how often it works, and it is WAY better.
