To be fair, these various visualizations are an interesting part of autonomous driving software (UI) development and to me they belong in this thread.
For example one of the Chinese robo-taxi visualizations posted a few months ago looks pretty nice, and I have to say that the Tesla design is coming a little closer to these others - increasing contrast, steadiness and completeness of rendering objects in the immediately relevant traffic environment.
One concern is whether the visualization design is pushed towards informing the L2 driver of the car's actual perception including uncertainties, or towards a cool and confident rock-steady Birds-Eye View cartoon that gives an L4 passenger something reassuring to watch.
Recall the disconcerting shimmering and jumping of beta 8, then the steadier but "graded-shade" lines and borders rendered in beta 9, intended to represent the actual level of the NN's confidence. Now in 10.2, we're seeing a yet-steadier and more confident rendering. I like it and it's great if it represents real Improvement in the NN confidence, but not if it actually suppresses the uncertainties. That is, we don't want it to contribute to any false sense of security in the L2 human driver, a pretty picture of a clear lane ahead as the car boldly accelerates towards Road Closed barriers as in Rob Maurer's first 10.2 video
Maybe the much-derided vibrating visualizations of 8.x were trying to tell us something important, something that was made easier to watch in 9.x but still delivering a true uncertainty picture. In an L2 display, we don't want them to hide that issue.
I would have exactly the same question about the ultra Cruise visualization as shown. Yes it looks good, bulut note that the presenter emphasized, even in the short clip, that this is an L2 system. So we could fairly ask the same question: is the pretty cartoon a good representation of current perceived reality, or is it filtered in a way that might inspire false confidence? To what extent are the road renderings a product of the car's own perception, or to what extent are they informed by pre-existing maps that only tell us "this is what the roads and intersections should look like"?
