Forget that crap. Download Waze on your phone get a vent bracket and use that. The crowd-based police and hazard detection is fantastic you get at least a 2/10ths of a mile warning for hidden or visible police. I use it all the time. But you need a usb adapter to keep the phone plugged in, though. Waze uses a lot of power.

Do you have a good 4k dashcam? I'd invest in one of the ones that has a 4k camera in the front and a 1080p one for the back window. You can get a nice one for $100-$150. Don't skimp.

I mostly use it on I-5 and main highways, and it's been amazing.

I just turn on Waze and stay full speed unless it fires off the warning sound. So, far, so good.

The only speeding ticket I ever got was in the late 1980s doing 120 heading home from skiing in Utah in a 65 dodge dart with a 318 V8. Happened by the bonneville salt flats at a speed trap. I was lucky I didn't cross into Nevada before that happened because at the time if the state didn't touch California it didn't go on your record. That, and the fine was only like $75 in Utah. I would have had an instant suspended license and a big fine in CA, but instead I paid $75 and it was like nothing ever happened.

This is common. I haven't told my kids 80% of the dumb stuff I did as a teen that should have gotten me killed or injured seriously. Don't want them getting any ideas...

And hazards in and around the road, including potholes in the highway (didn't know that last one until I got a large pothole ahead alert coming back from GSPF last weekend). The police warnings in advance are gold. BUT, you pretty much HAVE to have your phone plugged in to use it as it will suck your battery dry FAST due to the constant network usage and 3D rendering of the road and points on the road.

Everyone isn't driving alone. Plus, it's like two taps. All icons.
