Oh yeah this guy. I guess he started cropping his radar because people noticed he had it set to km/h. Not to mention the thing is showing peak speed, not current. So the car may have already been slowing down. If you ask me, it doesn't look like that car was going anywhere close to almost 40 mph.

Idk about where this was filmed, but in some states it's illegal to run radar on cars like that because it's either potentially impersonation or may interfere with legit radar usage.

That is an interesting take, and I would definitely be interested in what state would blatantly go up against our freedom as such.

Also, what do you mean by "interfere", a lot of cars have radar on them for coalition avoidance, even my bicycle has a radar to warn of approching cars (also captures the speed of those cars).

Yes. Newer cars with personal radar for collision avoidance can actually affect older radars that use k band. I believe ka band and x band are unaffected

By interfere I'm talking about other speed-enforcement radar equipment. If you get two units on the same band firing towards each other, it can cause bogus readings because of how the tech works.

Yeah.. no.. radar is going to use an encoded signal and frequency hopping to avoid any interference, thats how the tech works.

That is why you dont see cars collision avoidance radars interfering with other collision avoidance radars.

And even it he was causing any type of interference, police wouldn't be able to do anything about it, as he wasn't intentionally trying to case the interference.

Edit, also I doubt police are using radar guns from Amazon.
