Please, please would one of you beta testers post some new videos so we can move away the HD map topic!
Here is one I don't think has been posted where they did lots of testing of obstructions in the road:

It would be interesting if people also provided the Teslacam footage as well especially when it's dark or bright out. He does comment how the visualization shows his wife very early even though it gets darker, and she's wearing all black. From my recordings, the side repeaters can see things at night even without a direct light source, and the front camera picks up traffic light colors fine as long as the sun isn't directly behind the signal.

Similarly, this video up a mountain road at night looks extremely dark from the recorded perspective, but Teslacam probably has a much better view:
Yeah, at least for me, it's quite interesting to see when the visualization updates from a wrong curving road prediction to the correct T-intersection as the car gets closer and shines more light in less than a second:The intersection and road predictions are magical.

What I'd like to see, though I doubt we'll ever see it, or at least see it in HW3, is personal route HD maps. A human driver knows their regular commute fairly well. I'd like my car to build it's own HD or HD-light map of my daily commute. At the very least, retain the general geometry it captured while driving with more detail than typical GPS maps.
There is a dedicated video thread in the autonomous section so I don't see the point in cluttering this thread up with them. It is a good place to discuss one that has interesting behaviors though.Please, please would one of you beta testers post some new videos so we can move away the HD map topic!
Companies using HD maps don't use GPS for localization. As you said GPS is nowhere near accurate enough and is not reliable. They localize using LIDAR (Waymo/Cruise) or cameras (Mobileye). A car driving in fog so thick that no landmarks could be sensed would probably be driving extremely slowly.The trouble with HD maps as a way for the car to know what's out there even in dense fog or other or visibility conditions is that even with excellent signals from the GPS network, there's still a few meters of uncertainty as to the actual location of the car. With poor signal quality, there's even more uncertainty. And that doesn't even cover cars parked in no-parking zones or other new stationary objects. If the car can't locate itself precisely, it can't depend on the HD map for precise driving.
Another reason why HD maps is not a good way forward:
If you look at FSD videos, a remaining issue is the computer making it's mind up - left or right if a cone is in the way. The last thing it needs is being told the road continues straight ahead when their are cones ahead.
I would not be surprised if one of the uses for the data flood from the fleet, in particular once the new FSD architecture goes wide, is to generate maps with centimeter resolution where they are helpful, and keep them updated. You don't need this level of mapping for every meter of roadway, but there are going to be locations (particularly, complicated intersections) where knowing what should be there will help process the sensor inputs, in particular in challenging environmental conditions.
A particular car might only have the enhanced map data for routes it commonly takes, plus the general map that has flag bits that mean "this location is difficult, try to get the enhanced data before you arrive".
It may well be the case that getting to 10x human performance on the edge cases of the driving task within a reasonable power/computation budget will require this kind of assistance; effectively it's precomputing some aspects of the problem.
I hope they do this, but I haven't seen any evidence of this happening aside from peoples perceptions.
I'd love to see it taken a step further where it's not only continuously updates the maps, but expected driving speed/position that can be individualized.
As example during my drive to work I slow down before the corner before a traffic light because I know vehicles can get backed up to the corner so I need to slow down before going around the corner. The current version of AP doesn't slow for the corner, and continues going at my set speed. So there is about a 10+ MPH differential from what I'd do, and what it does.
Another example is I don't take the way the navigation tells me to go because that would force me to take a left onto a busy highway without the assistance of a stop light. The only reason the nav thinks its the right way is its trying to stay on the same street name.
The last example is on the way home I put myself into the right side of the road in one section for smoothness since the left side has a bunch of bumps.
I don't want it to duplicate all my behaviors. On one stretch of road I drive like a speed demon just because its suited to it. I'm perfectly okay with it doing normal driving there.
So ideally there would be a save, and replay drive buttons.

I wish he wouldn't speed it up so much.
