The squirrel issue is bogus. You are assuming it would slam on the brakes fior a squirrel, regardless of the situation, and would cause accidents, because you are trying to create a situation where the car would not perform well. Neither you nor I know whether or not the car would or would not react in Any particular way ... so making up fake scenarios to bolster a fake argument is pretty freaking dishonorable.
Look ... we simply do not know where AV tech will be in a year or three years. We can tell lies and invent arguments for ever ... what's the use? Just to fill pages with words?
What is the point of inventing fake scenarios to bolster fake arguments?
