Cool, so we've established that a full-time iPad guy is still allowed for level 4. Woohoo!
Every day, my mind is opening up to the smoke and mirrors created by all the other fsd developers.
It is so so obvious to me now who is actually ahead of the game.
It is just important to really understand that L4 is not necessarily better than L2. It depends on what you need it for. L5 is the holy grail, and everything below that is just different versions of trying to get to L5.
For instance, if you own your car, you probably love tesla's approach since you can use it anywhere you live(once it actually releases to the public). But you still have to pay attention. It would really suck to own a car in NY that only drives itself in Phoenix or SF.
But for robotaxis, all that matters is getting around the city you are in, so waymo/mobileeye are much better options.
Ultimately, competition is great, and it is fun seeing the different approaches to a similar problem. There is a ton of merit in all of them. As a tesla owner, I much prefer the tesla method because I can actually use it.
I would much rather a L2 everywhere over a L4 that is super limited.
And really, L2, L3, and L4 are all have enough similarities that you can "cheat" your way up the scale and deliver no actual usability if it is limited enough but still meets L4. For instance, someone could make a car that is fully L4 in a certain neighborhood in the US and it doesn't work anywhere else. Technically it is L4 in that area, but it is useless to most of the population.
I'd suggest stop worrying about what level is what and worry about the technology and what can the car actually do.
