I'm not sure what you're looking at here. There's no "tech demo" going on here. It's a new beta of technology replacing an old and quite well functioning technology that is a SAE level 2 system. This is not frozen in stone. In fact Tesla is updating it every ~5 days right now. There's many people that post daily videos of how Tesla handles on a specific road near them and you can see it improve update to update.
