So I recently started using Waze and I’m loving it so far! One thing I noticed that actually scares me is the fact that updating the map to report police, traffic or hazards requires so much attention - which is dangerous. I wish there was an easy way to do those map updates, that wouldn’t require me to take my eyes off the road for 10 seconds. One way I can think of is shortcut integrations for all of those things (so I could trigger it with Siri’s help by saying something like “Hey Siri, report police on the road”). I’m not sure if this forum is the best place to suggest features to app developers - if not that I would appreciate if someone could point me in the right direction.
Welcome to Waze 
It is possible to do but unfortunately you lose access to Siri - Using Hey Google to make reports
Please also know that quick reports are available. Upon long tap on Reports button you’re able to choose between police, traffic, and hazard.
If you wish to suggest a feature (like more Siri integration ;)) please search to see if something already exists and if not add your suggestion to the Waze Suggestion Box
