The newer Mercedes-Benz system will actually steer the car to keep it following the car in front, while in slow enough traffic (< 37 MPH).

Mercedes-Benz has a very nice product, but it's not hands-free. There's a huge difference.

That's the point here. Drivers will be tempted into a false feeling that the car is driving itself, just because it accelerates, decelerates and steers. MB has the same functionality, and I actually worry that it would cause even more distracted driving.

I think people probably said that about cruise control when it was introduced, and that turned out okay.

Define "okay." Cruise control has gotten "stuck" at 50mph[0], and electronic throttle control has left the throttle open disregarding user input[1].

So yeah, it's not some apocalyptic, universally-agreed failure that happens every day, but people have actually been killed[2] because the machine did something the driver wouldn't have done if they were in full control. (Maybe it's "compensated" for by deaths that were prevented by having cruise control -- I suppose we can't know for sure.)

I believe that's only for legal reasons. When the laws get sorted out MB looks to be in a great position.
