The Volt entertainment system may not allow local storage of DVD as video files, but I posted that it should allow recording video from the rear view camera, together with a recommended new dash camera. Then the system can store hours of images as the driver moves along the roads, recording possibly everything that happens in front, at the rear, and even inside the vehicle just for safety and accident documentation purposes. So if Volt drivers do get involved in an accident, they have the video evidence of what actually happened and confront any claims against them in court.
And if the Volt was borrowed (with or without permission), the interior view will document what the driver was doing (good for watching your teenage or young drivers).
