I use waze as a backup, and know it's only a tool along with others but the other day had a huge save. Sunday afternoon there's a 55 mph 4 lane highway always with light traffic (especially on a Sunday which was pretty cheap to be shooting laser on to begin with) I know waze alerts are usually about 50% reliable but on this one there were 5 reports. I'm like no way I can't believe there's a cop here, but with 5 I took it serious. I'm trying my damdest to go 55 there which felt like I was going 25, everyone goes 75 (no exits, no traffic). I see laser here literally about once a year. Way down the road I see him with (I presume) a laser gun he's holding like a set of binoculars standing outside his car. I never got an alert (rd mounted high) so either he shot me low or didn't at all being selective as I had slowed about a mile before. Anyway that would have been an expensive ticket. Protection in layers I always say.
