Current language models (misnomered as “AI”) are great at some things but fail at any real thinking.
Self-Driving works decently in predictable environments but anything outside of those limits can make it literally crash and burn.
Public road transportation by individuals just has too many cases where real decision-making is required.
Despite all their resources, I think they’ve given up. All the brilliant engineers and scientists have given up, because they know what we’ve suspected for a long time.
You don’t even need cameras, you need rails on the ground you know, car follows the rails. Also a driver maybe, if you have a driver it should work, you tell the driver where you want to go, they take you there.
Otherwise, you also can try a global satellite mesh, connected to laser squirrels that can tell the satellites what to follow, then it tells you have how to drive. But you need at least a nuclear power plant to run your setup, 59 giga server farms that are on high pressure, high fule mode.
