While driving to York’s Wild Kingdom in York Maine, Waze misdirected me To continue north on US 1 even as I passed the main entrance of the park. When I left the park, I had set-up a navigation to a eatery nearby. Waze said I was there when I was still a mile or more away!! Not exactly the best results today. Oh, and it never warned me about a traffic problem on I-95 after the Hampton Toll Plaza!
Looks like the AM of that area is not up with his work in corecting map problems. About the second problem, well, waze only tells about various road problems if someone sends info about that to the waze servers. To me it looks like you were the first to report it.
Navigating to POIs (points of interest) can be hampered by third party data out of the control of both Waze or any volunteer map editors.
Bing is the default search provider for POIs in the US. When searching for that business name in bing, you get a random spot further up the highway. This is most likely why you were sent the wrong direction. Unfortunately this is out of Waze’s control. Long term solution, get Bing to update it’s pin spot for this business. Workaround, change the search provider in the waze application (bottom bar on search results) and choose google. They have the spot correct based on searching their maps.
Results may vary. Issues are that sometimes the pin is placed directly on the business, and that pin is not next to the entrance road, Waze will then pick the closest road, which may be incorrect.
Since you didn’t give the eatery name, I couldn’t test, but most likely the same issue.
Traffic issue has already been answered. Traffic is provided by the whole community, if the traffic is not historically bad at this time, waze can’t avoid it, unless someone else has already been caught in it, and the system has the data.
