Oops, typo. it should read: "*anything* that suddenly appears in the vehicle's path, not just humans."
They put preview on postings for a reason, I guess I should take advantage of that...

You're assuming that the car will only recognize humans when determining whether to stop or slow down. What about animals that run out in front of the car, such as a deer? Would the car not stop or slow down because it's not human? I should hope they build in enough intelligence into the car to be able to stop or slow down for *anything* that suddenly appears in the vehicle's path, just humans. That includes such a thing as a moving "shrub."
