For people who are unconscious in the trunk (and here the notion of purposeful entrapment comes into play), Ford is trying to refine a carbon-dioxide sensor that detects respiration and sounds an alarm or opens the lid.
The carbon-dioxide sensor and heartbeat detector could also reveal the presence of someone hiding in the vehicle, which is certainly a security feature.
Because driver awareness is a critical component of vehicular safety, Ford put a bunch of pencil-sized cameras around a Lincoln Navigator and three switchable video screens on its large instrument panel.
The point here is what Ford calls "unprecedented front and rear visibility? which could enable safer driving in heavy traffic, while making the vehicle easier to park and maneuver."
Cameras on either side of the Navigator allow the driver to see around large vehicles to look ahead for hidden cars or pedestrians or whatever. The way Ford sees this system working, it would allow a driver making a left turn on a busy street to "more easily check oncoming traffic."
Rear-facing side cameras enhance the view of the adjacent lane, and four mini-cameras in a fan-like shape on the rear of the Navigator are combined electronically to "allow zoom and pan ability over a range of 160 degrees."
Another rear-facing camera (this one a NightEye camera) operates in low light when the Navigator is backing up to provide a detailed image of the area directly behind the big SUV.
