Someday there will be camera in cars, I know that Buick Lacrosse had a prototype system in it by Onstar and Verizon, the car had like 9 cameras and would film passively, but when something happened whether it was a carriage in a parking lot, or a door ding at your workplace the cameras in question would record back one minute up until the incident and a few minutes after, also the car would alert you to your smart phone, or e-mail that something happened to your car.
Here is just one of the many articles I have seen about it. I really hope something like this comes out soon.
