That is just one, but there are grounds for more. I talked with some of the people on the waiting side and they told me they don't want to sue outright because there's a certain stigma that's coming with it (witness the class action lawsuit thread for a glimpse of it) so they keep trying to talk Tesla into doing the right thing privately without involving the courts.There is in fact a class action about HW2 right now. The lawyer-proof-edness will be settled. Courts move slowly, but they probably will beat FSD to the finish line.
