There is a free waze you can run in the car's web browser. It's https://teslawaze.azurewebsites.net. Go there in your car, give it permission to see your location and it shows busy roads, police, tolls, rain, etc. You can open this in a computer webbrowser to get a sense of it.

This is someone's private project. They use open street maps, plus multiple open data sets. It's awesome, favorite thing to use in my car.
