If you can count on Waze to save you from tickets more power to you.
I've used Waze a lot and, driving on the interstates/freeways, I would NEVER depend on Waze alone to save me from getting tickets. There are thousands of miles of highways where there aren't many people driving (less populated areas) and far fewer Wazers in those areas. And night-time driving - forget about Wazers seeing cops.
My V1 has paid for itself many, many times over. Each ticket here in CA will likely cost at least as much as ONE Valentine 1 purchase (ticket plus increased insurance will easily exceed $400).
Enjoy Waze. I use it to see why traffic sucks. My V1 protects me from getting tickets.
