I think this is the edgiest case I've seen while using Autosteer. How do you train a neural net to recognize that the bright lines on the road are sunlight?

Haha. I normally don't look at the visualization while driving at 70mph. The car pulled hard right and I resisted which disengaged Autosteer. It would be cool if dash cam overlaid all the perception outputs and controls.Did your car’s visualization show the sunlight as lane markers?
I think I understand the reasoning here, but how does such a reconciling of conflicting inputs work in this case? For example, how does the car know to ignore vision input here (presumably listening to HD maps of lane markings), but know to listen to vision input and ignore HD maps of lane markings when construction repaints lane lines to shift them left or right for a temporary time?I imagine it would be very difficult. That's a good example of why other AV companies don't do vision-only. They know that it is much harder to handle these types of edge cases with vision-only. That is why they use cameras, radar, lidar and HD maps. Radar and lidar would not be confused by the bright lines and the HD map would also tell you where the true road lines are. So using cameras, radar, lidar and HD maps makes it easier to handle these and other edge cases more reliably.

Do cars (and associated data carrier plans) have the bandwidth for realtime HD maps?That would be done by the sensor fusion algorithms which would tell the car when to listen to what. In most AVs like Waymo, they fuse the camera, radar, lidar and HD map data early. So the car takes all the data and builds a single 3D view of the world based on all the data. In the case of construction zones, the car could take camera and lidar cues from cones, construction signs etc and the paths other cars are taking to know to follow the temporary lines and ignore the HD map. Also, the first car that encounters the construction zone could also update the HD map for subsequent cars. So the next cars that encounter that same construction could follow the updated HD map. The cars would be told that the HD map is updated.

I meant they have to be downloaded sometime, and if we’re talking about real-time updates then bandwidth matters. Even now, “normal” map downloads/updates are huge and take awhile.The maps are stored offline in the cars. So, the cars don't need a cell or internet connection to drive.
Mobileye claims their AV maps (which used to marketed as HD maps) are 10kb/km so you could easily store a map of all the roads in the world in the car.Do cars (and associated data carrier plans) have the bandwidth for realtime HD maps?
It seems the question of improving sensor fusion and solving with vision only (which currently still uses real-time non-HD maps) isn’t answered. I’m not convinced which (if either) is the best path to solving self-driving. I hope parties pursue (at least) both until either seems definitively not worth whatever cost/time/sacrifice in light of working solutions.

Are the maps preloaded into the car or does the car have to download maps every time it operates? Hopefully soon these cars will be able to cross state lines. Like NYC to NJ. or LA to LV.
