One of the optional features the software enabled was a pedestrian protection feature. The camera could detect pedestrians walking near the path of the vehicle to provide a warning to the driver.
I still remember an engineering manager walking into a morning meeting and saying something like this: "Hey guys, get a load of this. When we plug the camera output into a monitor and someone walks in front of it, the software brackets the person and it reads out TARGET in red at the bottom of the screen!" That's an interesting way to do pedestrian protection... or rather, it plainly was a carryover from the original purpose for which the software was developed.
Interesting.
