It's because they're trying to code the problem instead of solving it end to end. As you can imagine if you're trying to code driving scenarios you're never going to finish. Only Tesla and Comma.ai are on the right track. Think Alpha Zero vs Stockfish.

This problem has to be solved end to end. It can be done with just vision as humans can drive with just vision. It's literally just a software, machine learning and data problem. Just takes time

Except didn't Leela Zero (the closest thing we have to Alpha Zero anyone can actually use) beat StockFish, then StockFish was upgraded to use neural networks in a few edge cases and otherwise keep doing what it was doing and now StockFish is back on top? Seems like a Waymo-style approach is actually on top there.

Except Tesla is doing the exact same thing as it's the only practical approach at this time. The only place Tesla is extensively using general approaches is in building a model of the world from camera inputs. Other companies aren't doing that because they get much, much better results than Tesla simply by using lidar.
