I'd be in favour of a Settings option to select on of the following:
- Automatically report traffic
- Ask whether to report traffic (default Yes after 20 secs)
- Ask whether to report traffic (default No after 20 secs)
- Never automatically report traffic
I would then like a loud "bing" if either of the pop-up options are selected.

But I'm also in favour of an option on the front screen to suspend automatic reporting easily for a short stop - eg at a fuel station.

You need a Pause button. When I go into a store or get gas, Waze shows slow traffic

I would like the automated approach. I feel that Waze should be able to determine if I am on the road or not. If I am NOT on the road, it should at least not submit a traffic report. I realize that parking on the road would still be an issue where a 'pause' button would be required, but most other cases, an automated pause would be nice (or suppression of traffic reports).

I am very curious how this "pause" works when Waze runs in the background ;^)

My opinion: have Waze distinguish between "pause" and traffic by looking at the movements of the last 2 minutes.... if a car does not move at all, it has stopped for a pause; if it still moves 20-100m per minute, it is in traffic.

I agree. I often want to check something in Waze when stopping for fuel or other, so a "pause" mode would be great.

This could be extended to a more generalised "mode" approach - Driving, Walking, Cycling, Stopped/Parked etc. I noticed that heavy traffic problem too and was going to add something about a "Pedestrian mode".
