I use Google Maps for navigation, but I keep Waze running to take advantage of crowd-sourced data on speed traps and traffic cameras. Paired with my 9500ix and laser jammers, I feel confident in my countermeasures.
I also like reporting traffic cops when I can. Beats flashing your headlights.
Obviously not everyone has a smartphone, or is using Waze, but I have to wonder at what point will police start seeing a reduction in fines collected because of apps like Waze? Not that I care one bit, traffic cops can FOAD.
I could never get the voice controls to work to report things like hazards. Are there a list of keywords that will work or is it some technique?
