The way I see it is teslaq is saying that tesla needs hd maps comparable to the lidar ones google uses to work, whereas green is saying that tesla is using hd maps that the fleet automatically generated, but they are only used to aid fsd and improve performance
No, green is trying to have his cake and eat it to.
He claims to only report what he "sees" but instead what we get is him trying to redefine the terms to fit his desire of "how it should be"!
Because HD Maps are "widely used" and they "help a great deal" and according to him "the need for HD maps" - he jumps to:
Tesla must be using HD maps.
Talk about not keeping an open mind.
Note, his current argument, is "where did I say that"?
When he quotes TSLAQ cultists of using pre-loaded lidar-made HD maps and says, "say whatever you want"
Then when pressed, he can't accept that the NN's combined with geo-coded map data - like Karpathy said - could generate what he see in the beta videos, so to him, it must be "very precise maps" -- trying to yet again redefine "HD maps".
Yeah, all those road features, the cross walks, stop lines, traffic signs and more are recorded with great accuracy. If you reread what I said in the tweet, you can argue all you want this is not centimeter level accuracy, but it's at least multi-centimeter level or otherwise very precise.
Lastly, here is how Waymo describes their HD Maps:
Before our cars drive in any location, our team builds our own detailed three-dimensional maps that highlight information such as road profiles, curbs and sidewalks, lane markers, crosswalks, traffic lights, stop signs, and other road features.
This is what he is referring to when he says HD maps are "widely used"!
