Since the advent of computer-controlled cars, there’s always been the risk, however unlikely, that an electromagnetic pulse could brick your car. Now, in an effort to create a non-lethal way to stop a car, the Pentagon’s Joint Non-Lethal Weapons Program has reportedly developed a raygun that uses radio frequency and microwaves to stall a vehicle. The system jams the engine controller, effectively rendering the car dead.

Of course, this isn’t literally a handheld raygun. According to Defense One and Popular Mechanics, the JNLWP will have two different ways to mount the hefty system: in the bed of a truck that has a limited range of 50 meters and one that’s apparently three times bigger, with a longer range.

As the video shows, the system will also be effective in marine situations, but that doesn’t seem like the place it’ll see extensive use. No, more than likely these will be implemented at checkpoints and in other locations with dense crowds.

If you’re worried about the government stopping your car, you might want to get your jammer-proof points-style distributor car back on the road. Hell, you might want to do that anyway because summer is almost here.

Check out how this thing works in the video above.
