I'm not splitting hairs. The difference between L4 and L5 autonomy is enormous. I submit that you cannot get enhanced safety outcomes out of a system that cannot perform the task at hand at least as well as a mediocre human, and realistically not until you're routinely out-performing the bulk of human operators. And if you think not crashing into random shit in a perfectly chaotic environment is an easily solved problem please explain to me why store PoS tech (orders of magnitude smaller problem space) has been a roiling dumpster fire for decades now. Software doesn't have an amazing track record at solving problems. It has proven to be absolutely phenomenal at shifting problem spaces in weird ways and introducing spectacularly stupid unplanned side effects however.
