Use Waze all the time (when in service area). It's been rock solid for me in many questionable situations for routing. We were coming back from Ruby and it told me to get off of 70 onto 6 for a stretch. At the time I was going 80+ on i70 and I thought Waze was whacked.
Turns out there was a fire in the median and if I had listened to it, I would have saved myself 35+ minutes.
