Just back from a long road trip.
1/2 way through the journey, on a recommendation of a friend, I tried Waze.
Its way ahead of Google, particularly as it gives your current speed as well as the speed limit for the road you're travelling on. It also gives you warnings about obstructions coming up. It then asks you to confirm if the obstruction is still there.
Also better at advising you which lane you should be in in advance
