A good hypothesis, the sounds of the car do seem to be that of a Tesla... and the topic of self-driving could be interesting to update and go into greater depth from the issues he first raised in "humans need not apply".
Maybe this is a foot-note video to an upcoming main video. Footnotes has been released earlier than the main video before so there is precedent. Maybe it is going to be about transportation and the hundreds of thousands of hours lost to the grim reaper having to drive, when could have spent that time on something productive or entertaining if we had self-driving cars.
