Driverless cars are no place to relax, new study shows

This seems like... An obvious conclusion? Also since no level 3 or level 4 cars exist (besides the Mercedes in extremely limited applications), this essentially is untestable in the real world. How the car responds to a disengagement seems to be the key issue. Apparently the Mercedes gives you 10 whole seconds to respond... Which should be more than enough time to pay attention and put down your phone you're texting on.

I can say from experience, that TACC and lane keeping significantly reduces my mental load while driving, especially for long periods of time. Highway driving constantly requires you to center the car, and something that does that for you makes doing the rest of the driving (watching out for traffic issues, construction management, etc) much much easier in my view. That's only level 2, however. It still requires you to pay attention, it's just a different kind of attention in my view.

I wouldn't even relax driving near them. You never know when one of them will slam on the breaks for no reason or swerve suddenly. I've seen Tesla drivers say their cars will do that unexpectedly even while diving in manual.

It's like being a driving instructor --- your student will be fine much of the time, but will occasionally make fatal errors that you need to recognise and recover from.

Whilst I understand there is a place for studies and to demonstrate what we all think via the scientific method. But like others have said this is hardly surprising.

I've no doubt people who begun to fly on commercial aircraft where petrified for a long time in the beginning. Yes that's a whole other kettle of fish but still.

Driverless cars with a person who's supposed to be driving... are not what most people imagine when you say driverless
