Cars with level 4 autonomy do not require human interaction in most circumstances. However, a human still has the option to manually override.
In regular public roads.
How restrictive of a geographic region would still count as a YES here? For example, suppose Tesla deployed this for one particular neighborhood? One city? One state? What if it had a speed restriction, eg, only on roads with a speed limit up to 30mph?
And just to double check, no matter how good it is, if it enforces eyes on the road or hands on the steering wheel, that's definitionally not level 4, right?
On geographic region: I would count any public road (neighborhood or city)+ service being accesible to the public (including beta with non-employees). The speed limit would not be relevant as long as it is similar to the road speed limit
On Level 4 autonomy correct, to my understanding it should be possible not to have anyone on the the driving seat, no human supervision needed.
Thanks for your question :)
Note that level 4 means no human in the driver's seat. Waymo is level 4. Related discussion in the comments of this market: https://manifold.markets/NathanpmYoung/which-car-company-will-drive-betwee
How it is different from level 2? Level 2 can drive on most well market roads. Human have option to intervene. Level 3 for example differs from level 2, as human is not legally obliged to keep eyes on the road and hands on the wheel. Level 4 usually defined by list of 72 or something tasks it can perform without human be responsible for the outcome.
Roughly:
Normal car
Driver assistance like cruise control but eyes on the road and hands on the wheel at all times
More assistance like lane-keeping but still eyes on the road at all times
Driver can read a book or something but has to be ready to immediately retake control if the AI nopes out
No human in the driver's seat, the AI can always at least safely stop before asking a human to take over
Full human-level (or better) driving in any situation
