Agree 100%. This back and forth between fully-autonomous and partially-autonomous highlights the largest obstacles for "self-driving" car adoption.

The fully-autonomous route runs head-first into the inevitable, messy problems with software: security, maintenance, feature creep, complexity, unreliable networks etc. In theory, humans could nail all of these in car software. In practice, it's highly unlikely. The software industry can't even get basic security for IoT devices right.

The human-in-the-loop route runs directly into the only problem more daunting than reliable software: human nature. Human overrides for self-driving cars that need to be activated in a timely manner will not work. The drivers won't be paying enough attention to react in sufficient time. Note that overrides add even more complexity to an already fantastically complex system.

I still don't see what's wrong with current systems (driver assistance systems)

Say an always on self driving car, but it doesn't drive. Human has to drive, and the computer can correct any obvious mistakes the human does. Keep a really high liability for the car manufacturer though
