Maybe alcohol and sleep deprivation are clouding my judgement, buy I just had an idea...
Let's say, theoretically, that you don't care about throwing jam codes on LIDAR guns, you don't care about throwing jam codes WHILE jamming to gun, and you don't care about pissing off assholes who use the laser cruise control in their Infiniti FXs. In other words, you're me.
Now let's say you bought a ****load of infrared LEDs and mounted them to the front and rear of your car, wired them to a simple circuit board to fire them at 4 MHz whenever power is applied, and wired that board to your fuse box through a switch in your dash.
Now, any time you're driving the car, whenever you want to become immune to LIDAR (which may be from the moment you start the car to the moment you park, if you so choose), you are.
Is this possible? Is there some reason why the LEDs couldn't be mounted with enough cooling to sustain constant operation? Are there any problems I have not foreseen?
