I've often seen Waze 22.214.171.124 on Android getting confused as to which street I was, in Santa Clara, where there is no urban canyon or tree foliage, and GPS signal was strong.
Often, Waze would place me on a different street more than 60ft/20m away, even when I was stationary (parked at the curb of one street). My Galaxy's GPS position was accurate, and Google Maps correctly showed my location.
I've verified this multipled times and could submit screenshots, but I doubt that would help. Logs perhaps? Let me know if I can be of assistance, as this gets Waze confused and getting entire routes wrong because it thinks I'm on a freeway when I'm on a street near it.
