I use Waze. No radar detector.
It's a life saver.
Waze will usually alert to lazer, as cop has to be in a stationary position, usually for a prolonged period of time, therefore it usually gets reported on waze [if there are waze using drivers on the road]
Radar will alert to stationary vehicles who use radar and moving vehicles who use it.
Most local ticket in tri state area are radar.
On the GSP cops use both, it's more laser use up north and more radar down south, although laser has been migrating south as of late [spotty usage]
99.9% of the time cops using lazer on the GSP are in a major known spot or reported on Waze.
Radar really helps, you can even have installed a lazer jammer for full protection.
