I know Offroadaz is in the anit-track pack but I noticed when looking at the google map app for what was causing slowing on the I-17, it showed an accident as reported by WAZE users.
I clicked it and tried out the app while driving. Good is that it shows you where all the reported accidents, cops, cameras, hazards, jams, closures, and gas prices. Interesting is it can show you other users on the road (you don't have to sign in).
It has included navigation, speedometer and team options, stuff like that.

Highly rated on there.
