He particularly loves the (supervised) self-driving feature, a form of stress relief on long commutes.

Is it just but doesn’t that seem like a more stressful way to drive? I’d need to be at full attention so I could intervene at any time in case the car just starts doing something random. If I’m controlling the car I still need to pay attention, but at least I wouldn’t have to worry about the car doing something random. It seems worse than nothing.
