A very common use for these are to save you from getting a ticket when cities drop the speed limit from 80 to 40 for a few hundred feet, such as at the bottom of a hill to fatten up revenue.

I don't "speed" often (destroys mpg efficiency) and even then is typically 4-7 over. All of this is the well within the normal flow of traffic. Radar detector helps remind me to mind my speed and protect against the small chance that a cop may decide to penalize even a marginal speed overage.

Not everyone using one of these is the maniac going 20mph faster than everyone else, weaving in and out of traffic, though if a ban on these would prevent those dudes, then by all means bring it on.

I have 2 and they won't take updates any more. Just a year old.
That's weird I have an R7, R4, and R3 still taking updates. That's disappointing with the R8

Not sure if it's the detector or the program. I tried it on two computers and it says no detector.

You cannot ban these. It's like asking to ban people from listening to the person talking right next to you 🤣

I read up on it. It's something with the program not the detector.

Radar detectors are illegal in VA. I use Waze all the time, even when driving in other states. And it's free. Just saying, as an alternative to spending money on the detector.

I have both the R8 and R8w. These are probably the best detectors with the least false alerts. Make sure you scan for the radar guns used in your area or the areas you drive and you can custom filter all those false alerts.

The main upgrade is directional arrows that indicate where the signal is coming from. The R8 does have better range as well, but the R3 has more than sufficient range. I'd recommend an R7 over the R8 if you want to upgrade to arrows.

This vs Valentine? I really like that Valentine will updates units instead of having to buy a new one every time new tech comes out.
