You can adjust that in your settings, to a limit. You can set the distance on how far out you get for notices. I like to know what's going on around the city in case I decide to go a different way than Waze has me going.
For instance, I was on my way home and opened up Waze to send me home. I started driving, and at a red light, was looking through the reports and found a major accident on the Interstate I was going to get onto. The accident was in the opposite direction from my direction of travel, but I knew traffic would be bad, so I immediately got off the road I was on and took a different route home (with the help of Waze to get me through some back streets).
Just wazeting my time to help you waze your route smoothly.
