Human vision is limited to a ~180° horizontal angle (Figure 1) and an even smaller vertical angle.
This means you can easily be blindsided by objects coming from behind you. In ancient times, this was less of a worry, but with electric cars, electric scooters, and bicycles, there are a huge number of fast-moving and potentially-lethal objects that humans must be aware of.
Since cars are now the “apex predator” that is ranked above humans in the food chain, humans should adapt and become prey animals. This requires a visual adaptation to allow for 360º vision, which can be accomplished as shown in Figure 2.
The example in figure 2 requires complicated electronics, but there’s probably a way to create an optical 360º-vision system that uses no electronics.
A similar product already exists: rear view mirror spy glasses—inexpensive sunglasses with mirrored “wings” that allow you to see behind you.
PROS: May reduce the number of deaths and injuries from accidents caused by a lack of visual situational awareness.
CONS: Can the human visual cortex handle this type of input data? Only one way to find out—experiment on some undergraduates.
