It would be very good if we could pin a section of the road that we passed 15 to 30 seconds prior (i.e, to warn other drivers of hazards etc. that you passed previously). For example, we hit a large object in the road when I was in another app and by the time I got to Waze, I knew my post wouldn’t have meant anything if I posted it at the present location. Being able to scroll back and say, “There: there was a police officer, hazard, etc back there” would be great. Also, occasionally an “undo” button would be useful as well.
This was proposed several times, I also agree with you.
Just to give us option to atleast click 100, 200, 300m ago Police, Hazard or something
