Other gripes:
It suggests using HOV lanes despite not knowing if there is someone else in the car, that can dramatically effect routes (say route A is faster only if you can use the HOV lane).
For ferries (I live in Seattle) it doesn't count the time on the ferry which can give you wildly incorrect time estimates. There's also not a way to ask for a route that doesn't include a ferry (sometimes you can drive around). For example Google Maps suggests 1:04 to get to a spot on Bainbrdige for me right now where Waze says 25 minutes. Considering the ferry ride itself takes ~30 minutes...
@jonknee is your name jon kneeland? I'm a John Kneeland. Small world!
There hasn't been any news on this for a while, but Waze has also stayed almost exactly the same. There's a little integration the other way (Google Maps sometimes shows incidents reported on Waze), but that's it.
