If more people used waze this would be a cool natural experiment: Does priming people to think a road is dangerous increase the number of crashes? There are self-fulfilling prophecy type effects in psychology. I can see how making people more anxious could do that. Also could see how removing the more risk averse traffic from certain stretches of road, would make the traffic that remains more dangerous; fewer cars leading to greater speeds. I feel like waze and other “people engineering” apps don’t fully grasp their responsibility in shaping human behaviors.
