The demos are all totally staged, but it is disappointing that Tesla won't show us anything to raise spirits.
Today's staged GM demos appear to be the most impressive, but they also didn't show any camera views with object detection to convince any engineers that they are doing any more than following a rigidly pre-programmed course with staged pedestrian traffic. The last Tesla demo was a standard Mountain View joke with off-the-shelf 2016-era demo ware. Every player has those.
All we know for sure is that Tesla isn't doing any FSD miles in CA because they have to disclose progress and disconnect rates, and they only did a tiny number of miles with LOTS of human takeovers months ago. We can only hope that they are at least working on L3 and L4 features and testing somewhere, but for now, there is zero to go on. It doesn't particularly bother me that they are not doing FSD demos, per se, because that isn't essential in building the technology. They could be doing LOTS of miles that don't count as FSD but are providing training data and validation.
Objectively, it pretty much looks like nobody is ahead with a commercially viable solution and all the high-end cars and EVs will probably offer similar capabilities somewhere around 2020-2022, if we're lucky.
