Overall, it's working pretty well, with a few annoyances:
- Lane changing recommendations need improvement. Will frequently nag you to move out of the leftmost "passing" lanes - which we'll usually ignore in heavy traffic to minimize how many times we do unnecessary lane changes.
- Tendency to guess wrong on the speed limit resulting the vehicle slowing down unnecessarily, which is bad when you're in the middle of heavy traffic all moving at much faster speeds, and the vehicle behind not expecting you to rapidly slow down
- Will sometimes wait until just before an exit ramp before recommending a lane change over to the rightmost lane
- Will sometimes warn you when you are entering a construction zone, but then doesn't provide any warnings that you are still in a construction zone
And, still don't trust the software when the lanes are narrow (usually in construction zones), the lane is close to a traffic barrier, or there are inconsistent or difficult-to-see lane markings.
This is still beta software - anyone using NOAP should maintain control of the vehicle, because the software could make mistakes...
