FSD 12.3.6 took my Dad and I curb to curb to see Grandma and back with zero interventions
FSD 12.3.6 drives the author and his dad to visit Grandma and back, including a U-turn and parking, with no interventions.
We had to go give some flowers to my Grandma, and I didn't do any driving. The system drove us all the way there, made a U-turn, and then parked. Then it drove us all the way back and parked too.
Explain to me how a driverless or "Level 4" system would be any different from what we experienced here. And explain to why none of the Level 4 services like Waymo can do this drive for us, and when they will be able to.
