>they do track object across video frames which for me it's the minimum a system like this should do. All previous FSD systems are just Fake self-driving.

I'm pretty sure Waymo does this. It's hard to imagine not using this information, it's basically 50% of what I do when driving (e.g. that kid that was running on the sidewalk suddenly disappeared from view in an unexpected way; I wonder if he's about to cut across the street, etc).
