Tesla has been attempting to build AI-enabled cars for the past two decades, yet it remains at Level 3 autonomy, significantly short of reaching Level 6. The company has been facing regulatory challenges across various regions of the United States of America. It's not just Tesla; other companies such as Cruise, Waymo, Aurora, and others face similar issues. In addition to autonomous vehicles, other experiments like Hyperloop One and Boring Company have also fallen short of fulfilling the lofty promises they made regarding human transportation.
