The juicy bits:

"it can get confusing to understand what’s so special about a Mercedes system that only operates on certain stretches of Germany’s Autobahn network, and only up to 60 km/h (37 mph)."

"but it can’t perform lane changes indecently"

The lane change quote is to describe a level 2 system by contrast, which implies this system can do lane change.

Full quote: “Right now every other car claiming to have advanced autonomous features is currently only at Level 2 at the most, which means the car can stop steer and brake in certain conditions, but it can’t perform lane changes indecently and the driver can’t remove his hands from the wheel for extended periods.”

But yes, speed limit reduces usefulness to congested traffic situations as also noted in the article.
