If they are setting an objective measurement, how is that an illusion of control? In fact it seems like exactly the opposite - they are putting hard numbers on the level of risk they consider tolerable. They are making that available to everyone so they can debate and dispute it. If anything, this is removing the illusion of control. The illusion of control would be to say you would never trust self-driving cars. Saying you will trust them at a level of 5x measurable safety criteria above human drivers is totally different. Now we can make actuarial arguments about whether it should be 5x vs 2.6x vs 0.9x and debate how to measure the safety criteria - that’s a completely different world from one where people “feel like” human control of the car is safer.
