+++Waze has better traffic detection and alternate routing than GM and AM, in my opinion, which is the reason I use it over them.
--Waze needs a way to mark your parking spot any time you arrive anywhere. Sometimes it's there, sometimes it's not, like when you stop somewhere other than the routed destination.
+++The arrival time estimate is excellent.
--The pop-up ads are TRULY OBNOXIOUS and basically stupid as others have pointed out.
+++The police AND STOPLIGHT CAMERA warnings are helpful.
--The ride sharing button is way too prominent and a waste of valuable UI territory.
--The hazard reporting requires too many clicks. I just noticed the "OK WAZE" feature and haven't had a chance to use it yet.
+++The alternate routing view, with the ability to see multiple alternate routes and their estimated trip times is excellent, too.
