While 360 is great and needed, I'm of the opinion that a more robust camera system is needed that not only allows the human driver to see what is immediately around the car, but also allows the computer vision system to accurately asses what is a occurring around the car or better to say what is on a collision course. Think about when you are driving in tight spaces and hit something that you didn't see. Especially when you do something that you think is easy like exiting a parking space, but you forgot about small ballast sticking up and crazy scratched your rear bumper. If the vision is good enough you could control longitudinal actuation so the system could not only warn you but actually stop you from damaging the car or hitting anything. Essentially the system would only allow you to drive on smooth roads. Imagine a system that would be good enough to not avoid potholes or even figure out the best maneuver to get into and out of tight spaces.
Maybe a better way to say it is that while it is great that I can see what is going on around the car, I'd rather the computer do it and warn me when appropriate as well as actuate the controls when collision is calculated to be close to imminent so as to keep me from touching the car to anything but smooth road.
Not only that but a smart camera system could easily monitor the car while it is parked. Think vandalism or a parking accident; imagine anything that is moving outside the vehicle is captured on video, processed locally to determine what the intent is, then smart decisions can be made like stream the video to your phone so you can make an informed decision about what the car should or shouldn't do to deter.
Wouldn't it be great to know that your car is looking out for you? How much would you pay for these features?
I don't know about anyone else, but just thinking about the cost to repair a few curbed wheels, minor door dings and small scratches is worth quite a bit, not to mention the peace of mind that you could basically see something even before it happens.
