Attaining level 2 has nothing to do with attaining level 4. A camera that reads the road lines has nothing to do with the AI necessary to traverse an intersection. They are completely different paths, not any sort of continuum. They are distinctly different problems. An analagy would be changing a tire - I could reach perfection in jacking up the car, but if I can’t get the lug nuts off, I still can’t change my tire. And my jack does nothing to get the nuts off. I have to go back to square 1 and find a tire tool...and if I cant find one I’m just stuck.
Tesla’s concentration on level 2 is more indicative that they have less interest in attempting level 4.
No it is a continuum. The camera is part of the data to gather. Reacting to the camera is part of the processing of the data. In the end that’s ALL this is: gather data, use it, do it all fast enough to safely control a vehicle at highway speeds.
Tesla’s focus on level 2 is indicative of the fact that they’re willing to ship in iterations. They’re climbing the hill. And so is BMW, Google, Mercedes, Volvo and Ford. And whoever did these trucks. And that’s just the ones we know about.
In the end all purely technical problems are solvable. It’s not like they have to break relativity or thermodynamics. It is, at it’s core, a big data problem, and big data is a happening place right now.
