Which is precisely why so many people are critical of the term "fully autonomous".
> 99.999% cases covered
What cases? The point is that edge cases are the issue with autonomous driving. I can fall asleep on a train or a plane because I know there is human conductor who can handle the edge cases. This doesn't exist with L4. Everything else that doesn't let me fall asleep (read a book, look at my phone, etc.) is only marginally better.
I've always thought of L5 as a car that can operate via its sensors + onboard computing alone, at least as well as a median human driver.
No communicating with a server to download maps, no perfect performance, just a car that knows the state's traffic laws driving a brand new road in any reasonable weather, and getting into less crashes than a human would.
Not really. L5 is impossible, period.
What I think will happen is L4 with 99.999% cases covered and have it come to a safe stop for the 0.0001%, assuming there was a way to safely stop.
L5 which means 100.000% covered, will not happen, but the PR people will continue to use the term.
