With all due respect, now you've lost me. Tesla could add more sensors to the point of overkill. They could add more compute power. They could also rely on hi-res mapping. Is your point that no vehicle company will achieve L5 autonomy without a ridiculous geofence?
If it's so easy how come no one else in the world has done it?
A lot of this comes down to defining both what you want something to do, and constraints.I did not say it was easy, I said it was doable. And there are others that have done it. I believe Blue Origin does it too.
FSD is pretty bad in California too.. chooses the wrong lane all the time, for example.
It's remarkably akin to early computer vision attempts... pre-2012, if you wanted a computer to find a car in an image, you'd hand-write some set of feature detectors for bits and pieces of a car. The round shape of the wheels, the brake lights, the contour of the hood and roof, etc. And then sort of sum everything up and tweak it until it has tolerable performance. It will be super brittle and break easily and it may seem like an impossible task without constraining it. But now adays that would be an incredibly foolish approach. Today you'd load up PyTorch and train a CNN to detect cars in an end-to-end fashion, and not fuss over individual features. You'd fuss about the data set and fiddling with network parameters, fixing bugs, but you'd definitely not be concerned with the individual features, you're designing the system in a holistic way.A lot of this comes down to defining both what you want something to do, and constraints.
When both of those are tightly defined Engineers can generally pull off even difficult things given the opportunity to fail, and to try again.
The problem with generalized autonomous driving is there are no constraints. So you end up with a million different variables, and all kinds of things you have no control over.
It's basically an impossible problem to solve unless you scale it down to things you can control, and things that can be dictated by regulations.
This is exactly what MB did to achieve L3 in Germany, and hopefully this year in Cali.
It might not be much, but at least its a starting point. Something they can build from.
How would you classify a completely autonomous vehicle if its autonomy was limited to California?First of all, nobody is suggesting adding sensors to the point of overkill. That is a strawman. I do believe you need adequate sensors and HD maps in order to achieve safe and reliable autonomous driving. And I do not believe 8 cameras that are only 1.2 MP and the current 144 TOPS FSD computer are adequate for safe and reliable autonomous driving. So I do think Tesla needs more sensors, more computing power and better maps than what they currently have but not to the point of overkill.
Second, if you geofence, then your autonomous driving is L4, not L5. So it is literally impossible to achieve L5 with geofencing. Please understand what the levels mean. Put simply, L4 is autonomous driving with some restrictions like geofencing, L5 is autonomous driving with no restrictions. So when Elon promises L5, he is promising a self-driving car that can drive anywhere, any time, in all conditions with no human intervention ever. Nobody has L5.

....AND geofenced.
I was thinking (incorrectly) that L4 didn't require geofencing, just basically human takeover. Looks like that should/could change at some point, maybe in "two weeks" or by the "end of the year".Yes but that is already implied when I say "L4".

Whoever comes along with the first fully autonomous car will probably do the same thing, they're definitely not going to fuss over the taxonomy of traffic cones, or the minutiae of lane markings and signs. They're not going to have dozens of discrete planners and state machines, and tree search. They'll show up with the right network architecture, a massive dataset, and just a little bit of C++. Perception, prediction, planning all in one. It'll be like the MuZero of driving cars. And then months later everyone will be able to make their own fully self-driving car in PyTorch by just following some tutorials on a web page. And then all the billions spent at Waymo, Cruise, Zoox, Tesla FSD, whoever else is left, would have been completely obsolete and wasted effort. Just like the first attempts at computer vision are obsolete relics that no one cares about anymore.

The sustained and ODD-specific performance by an ADS of the entire DDT and DDT fallback without any expectation that a user will need to intervene.
I meant "just basically [allows] human takeover" as in L4 MUST have steering and pedals in case needed, and you can manually drive the car. In L5 they are not required and NEVER needed.L4 does not require any human takeover. It is actually mentioned in the SAE definition:...

Good one. Sounds like the same advice that politicians getLong ago, I used to work at a radio station as an announcer. The Chief Announcer's advice was, "If you make a minor flub, just move on like nothing happened. People don't listen that carefully and forget quickly."
Yeah, it’s a fantasy that is being described.You seem to be describing end-to-end learning.
The L4 podcars (Cruise Origin, Zoox whateveritscalled, etc.) don't have steering wheels. Before the Origin GM pitched a L4 version of the Bolt with no steering wheel...... as in L4 MUST have steering and pedals in case needed, and you can manually drive the car.
Let me amend my horrendous mistake.The L4 podcars (Cruise Origin, Zoox whateveritscalled, etc.) don't have steering wheels. Before the Origin GM pitched a L4 version of the Bolt with no steering wheel.
Waymo makes it very clear their remote monitors cannot drive the cars....as in L4 MUST have steering and pedals in case needed OR be accessible by a remote control team that can take over and drive the car.
