It's a matter of expectation. Teslas have a steering wheel. You are still the driver. Full self-driving is more like extreme driver assistance. It's like an airplane's autopilot. It does most of the work, but the pilot in command is still ultimately responsible for the safety of the flight.
By contrast, Waymo does not have a steering wheel. You are not the driver, you are a passenger in a taxi.
Two different approaches, both valid. Both possibly necessary; these technologies don't emerge fully formed.
