Sorry my intent was for you to confirm if either question is true from your standpoint.
So I'll try it a different way.
What is Tesla going to have to do to get beyond L2?
Write actual self driving software, instead of an ADAS system (which is what fsdb is)
I really am lost, because when I asked if they will be able to expand the existing FSD Beta code, it sounded like you said no.
Probably because Tesla, also, said no. Explicitly.
They plan to develop something, that is not fsdb, in the future, that would, offer L3 or greater capabilities.
So I thought that the other option would be that they would have to rewrite all the code, for which you seemed to say no to as well.
Why in the world would they need to do that?
Recycling parts of your code when doing a new project has been a tradition in programming for...basically ever.
Video game companies, for example, often take the code from a previous game- sometimes just parts- sometimes the entire game engine- and then use it as the basis for a future-- more advanced-- game to which they then add additional things in said new product.
It's pretty rare anybody throws "everything" out
The fact, to pick one specific example, the vision code recognizes and reads speed limit signs does not grant any particular level of driving automation- but it's useful, working, code... so I'd certainly expect them to use it in the new >L2 software... though they'll obviously need to build further so it can handle more complex signs it currently does not. Tons of examples of things like that in the current code that'd be moved at least in part to a new system.
What is Tesla going to have to do? I really want to hear your input.
For level 3? Write software with a complete OEDR.
Which fsdb, even in its final version, is not.
They'd also likely need to improve significantly some of the current things that ARE in fsdb.
For L4 they'd need that PLUS robust DDT fallback code to eliminate the need for a human at all in the system.
This all assumes the hardware is capable of the job of course... HW3 almost certainly is not. It's unknown if HW4 will be-- there's certainly problematic blind spots in the HW3 system...problematic for parking, and for some poor-visibility intersections as well... and it's unclear if those are "fixed" with 4 or not.
Since nobody in the world has developed a working L5 self driving system (or even a general, not massively restricted and geofenced, L4 one) nobody actually KNOWS how much hardware you need to achieve it, regardless of your software.
