Imagine a driver driving down a parkway at speed and thinking "I'm on a parkway, so I should shift the car into Park."

That's how dumb that argument is.

If a driver ignores the requirements of their driver license AND the vehicle's clearly worded warnings, then the driver is entirely responsible. Claiming that the driver is not at fault because they interpreted the word "autopilot" to mean "I can disregard my responsibility as a driver and ignore the vehicle's very clear warnings" is absurd.
