Sincerely asking. Doesn’t that mean it requires driver attention?
- jessriedel 10y agoI don't think so, mostly because I don't think a qualifying system would actually require an instant switch over. I can't find anywhere that it the timescale is defined; if I had to guess, I'd say it's defined in terms of whatever the minimum safe timescale is (empirically), i.e., Level 4 is whatever it needs to be to allow a human to read a book safely, but not necessarily sleep. For instance, a Level 4 car probably can't deal with unexpected road construction, and might simply bring the car to a halt, smoothly but quickly. It would be dangerous if the driver was asleep and the car stopped dead on the highway for the 30 seconds it takes someone to wakeup and get oriented, but it could be pretty safe if the driver just needs to look up from their movie and grab the wheel. That's just speculation, though.
