If you're looking for a good route from Olive Ave. to Brookside down Buena Vista, you'd better consider using your natural geographic intuition rather than Google Maps:

There are quite a few problems with Google's 'new' data. Well, the long story is the data dates back in places to the 1980's, but since they've 'found' all this data, some of it bad, they can call it their own.
Anyway, you can report problems with the data if you want. They still haven't fixed a few things I pointed out to them a while back.
