It seems to me that somebody could make a lot of money with a car accessory.
A digital audio/video recorder that would be wired to five pinhole cameras/microphones, the four sides of the car and one of the outside of the driver’s window.
A simpler version would just have two: one of the rear of the car and the other of the driver’s window.
It would be discreet enough for no part of it to be detected during a regular search of the car by police.
And it might even be enabled so that once it had been activated, and “run out the clock”, say three hours of recording time for each camera, without being turned off, then the system would search for an open WiFi to connect with. As soon as it found a stable WiFi, it would transmit its video/audio to a third party.
This might even mean the end to "puppycide".
