Could you developers make it to where in the PS4 version, when you are being chased by the cops the Ps4 lightbar flashes red, white, and blue like a police lightbar. This could be easy to make and implement.
It would be really assume if you could buy a radar detector for your car. Than when a cop or civilian is using a radar detector on you the light bar starts to flash and your speaker on your controller starts beeping like a real radar detector.
