For reports such as police ahead, why not allow the not there or still there response go a bit past the report point.
Quite often, for police reports etc we cannot say whether the incident is still there until we reach the report point and by then the incident confirmation has disappeared. How about allowing the answer past the report point - perhaps for a further half minute or so.

Yep - totally agree with this, the length of time to select "There" or "Not There" needs to be increased substantially for all of the reports.
I find the current length of time available too short and has me choosing between watching the road or quickly looking for the reported item (car, police etc) and then having to quickly try and select either There or Not there as appropriate as I know the time that Waze gives me to respond is very short. I feel that this is influencing dangerous driving.
The alternative that I have decided on, is simply not to try and select either, as I dont want to have a crash trying to quickly update Waze.
