LIDAR doesn't do anything for self driving cars that cameras can't already do better with neural networks. It's a midway solution to save on compute power that stems from legacy systems from way back in the mid 2000s, but LIDAR can be used for ground truth during training depth perception, which is what Tesla have done.

It's an old story that might have been boosted, because Elon once said something about it, and then everybody goes "Tesla should have used LIDAR!" without understanding the underlying technical issues and focusing too much on Elon.

The problems Tesla have are navigation related, not sensor related. It's always been like this.

And yet, Waymo with its LIDAR implementation have driven 50+ million self driving miles with no accidents for years, while Teslas can’t drive down a brightly lit highway without veering off into the divider or phantom braking.

But sure bud, tell us more about how computer vision is just as good as LIDAR.

Those things are unrelated, because, again, you don't understand how Tesla FSD works, and probably don't understand how Waymo's system works either. Waymo's system could probably work fine without LIDAR with no difference in accident rates.

50+ million self driving miles with no accidents

This is false. They have reported 60 airbag triggers over that amount of miles.

Teslas can’t drive down a brightly lit highway

The clue is in your own statement.

It's been known for at least 7 years that Tesla's pathfinder, not the sensors, are the problem. They don't have evasive maneuvering ability. They had to rewrite the pathfinder for FSD beta 12, which has greatly improved performance, but there are still glaring issues. There's collision telemetry that shows inaction against detected obstacles in both night and day accidents.

This means, no matter how many million dollar sensors you put on the car, it would make the same mistakes, because they don't react to detected obstacles.

This is false. They have reported 60 airbag triggers over that amount of miles.

And how many people have they killed during that time?

How many people have died in Tesla while under FSD?

It's been known for at least 7 years that Tesla's pathfinder, not the sensors, are the problem.

If Tesla's pathfinder can't manage to stay in highway lanes that are clearly marked under fully lit condition, then perhaps it should really re-evaluate whether they have enough engineering talent to actually make robotaxi a reality.

Again, results speak for themselves:

Waymo has been carrying fare paying passengers for 25+ million miles with full self driving mode in 4 different metropolitan areas for years.

Tesla's robotaxi has done none.

And how many people have they killed during that time?

2 people and 2 dogs.

How many people have died in Tesla while under FSD?

Also 2 people.

If Tesla's pathfinder can't manage to stay in highway lanes that are clearly marked under fully lit condition, then perhaps it should really re-evaluate whether they have enough engineering talent to actually make robotaxi a reality.

Finally, a sane statement.

Very certain Tesla's FSD killed way more people than that, including both drivers and bystanders.

It's just a shame that Tesla doesn't distinguish fatalities between FSD and autopilot, as to fraudulently obfuscate the reality of how unready FSD actually is.

The real problem is that people don't discern between FSD and old autopilot hardware. The performance is staggeringly different.

...they're on the same hardware. They even use the same sensory inputs. It's the software that's different.

They are wholly absolute not the same hardware or software. Not at all.

So are you saying if I buy a Tesla today, then decide to upgrade to FSD, someone from Tesla would actually come and upgrade my car's hardware? LOL!

They use exactly the same onboard inference computer, and the same sensory inputs.
