Waze doesn't tell you what speed to drive. It just gives you a direction, and you're literally at the steering wheel. If you're breaking any limits, it warns you, quite loudly by default. However, it does give a reasonable ETA based on real world traffic conditions, and that's a good thing - if today on some street everybody's driving at 10mph then it doesn't matter if it's because of a traffic jam or unsafe icy road, Waze won't send me there.
