Ford BlueCruise and Mercedes Drive Pilot are equipped on some ICE vehicles, and are hands-free driving on (some) highways.
Mercedes Drive Pilot is classified as L3 which is better than Tesla or Rivian.
Try to find videos where people actually use it. A handful of 1 minute long promotional and car reviewers' videos. It's mostly a marketing move.
"DRIVE PILOT can be activated in heavy traffic jams at a speed of 40 MPH or less on a pre-defined freeway network approved by Mercedes-Benz. DRIVE PILOT operates in daytime lighting conditions when inclement weather is not present and in areas where there is not a construction zone." [0]
