Children moving around the back side of cars in parking lots for example. I find myself always being extra careful when backing up in eg Target or Walmart parking lots for this reason. Seems like an ideal use case for cameras.

Let's not forget these systems typically have a distance sensor setup with audible tone. Having some more accurate gauge of obstacles and their relative distances and the improved visibility is a no brainer. When I read this headline the first thing I thought was "good, finally."
