>Or perhaps, VW exec hopes full self-driving cars may never happen, because it would imply a fleet approach where transportation would be a service instead of cars being a prized possession.
Cuts both ways. Tesla execs have the same reason to overhype autonomous driving, because their market value depends on being perceived as a hypermodern tech company.
So far reality has proven VW right. Elon himself had to walk back on grandiose claims about full autonomy and robotaxi fleets, or advertising cars with slogans like "the driver is only there for legal reasons, the car drives itself" a bunch of years ago.
Full autonomy on a human level requires human levels of intelligence and 'common sense', it's a ridiculously hard problem that requires several leaps in AI and plenty of other fields.
