Not Worth Lifetime Updates!!!
Map errors are frustrating when they happen to hit an area that's important to you. I've been thrilled that I can correct my local copy of my TomTom map -- something I could NOT do on my Garmin 755t (I don't know if Garmin allows that on newer devices?). Having the 1xxx and 2xxx devices be able to access community map error corrections will be great -- but for now, I'm really pleased that I can at least correct my own copy.
So far, in about 3,000 miles of driving, the map in my TomTom Go 2535 M Live has been more accurate than any prior map I've used. Not 100% perfect -- but remarkably so.
Out of curiosity, I thought I'd try pluggin a few of your neighboring street names into MapQuest. I tried Powhatan Lane, Forest Ridget Drive and Calvert Lane and found the neighborhood. Lo and behold, Mapquest is also only showing partial completion of Forest Ridget Drive. I was amused, as a matter of fact, to turn on the satellite image and see that it's up to date, even though the depiction of Forest Ridge Drive is not on the map. Map updates, to date, cannot keep up with all road changes around the world -- that just hasn't become reasonable yet from a cost or logistics perspective. GPS vendors have to choose who to partner with or acquire for maps. Some will have your neighborhood or destination mapped correctly, and some will not. I don't think there's a general consenus at this point that any one vendor's maps are significantly better or worse than the others. Whether you run into a map error where it bothers you is essentially a matter of chance.
Anyway - Here's what your neighborhood looks like in Mapquest:
