Using Waze already feels like playing roulete. I set a destination while in my driveway. It decides my current location is one of the side roads behind my house, so right off the bat it's a 50:50 chance that the direction I go when I leave my driveway will be correct. Then, while getting out of my driveway, it will reroute, then probably reroute again once I commit to a direction on the road. It also tries to direct me to a precise location in a parking lot, instead of the business itself. I've parked at my destination and it's still trying to reroute me through the lot.
Waze is great for road conditions and locating construction, hazards, police, etc but it is lousy for navigation.
