To be fair here, and for people who might not know, Teslas do not "autonomously change lanes". When autopilot is active, the driver must initiate the lane change themselves, and it's the driver's responsibility to do so when it's safe. Tesla does not claim otherwise.
The article actually discusses the lane change feature specifically. He argues that, if the car requires the driver to look and confirm that the lane change is safe, you're probably better having the driver be in control of the whole process.
As a driver, this makes sense to me. I've definitely had cases where someone driving quickly "has appeared out of nowhere" while I'm changing lanes. I'd much rather be fully engaged in the lane change process and prepared to immediately back off than to have given an autopilot a thumbs up and let it handle the details.
