The phantom braking issue with auto pilot tells me it can’t. A shadow from a tree doesn’t trigger your brakes locking up at 70+ mph when there’s a lidar sensor to tell you it’s not a physical object.

“Just buy FSD” isn’t a reasonable answer to a problem literally no other automaker suffers from.

How do you explain the reports of Robotaxis running into fixed objects? If what you are saying is true that shouldn't be able to happen.

Luckily everyone else in the comments is an expert. And also doesn't recognize that Tesla's already drive themselves and did not need Lidar. They also mischaracterize the reasoning.

Well, you did get a chuckle out of me, so that's something!

Yeah it's BS. Tesla uses lidar where it makes sense: They have a small lidar fleet to collect ground truth depth data for better vision estimation. This part is long solved.

> I'm not sure what would be wrong with the vision system that lidar needs to fix.

This conversational disconnect is as old as the hills:

1. Person 1 asks "what's wrong" (if it ain't broke don't fix it)

2. Person 2 wants to make something better

My meta-goal here on HN (and many places where people converse) is for people to step back and recognize the conversational context and not fall into the predictable patterns that prevent us from making sense of the world as best as we can.
