I might challenge with "autopilot is cruise control." To me, Tesla is marketing the feature much differently. Either way, looking up the definitions of each:
"Auto Pilot: a device for keeping an aircraft or other vehicle on a set course without the intervention of the pilot."
"Cruise Control: an electronic device in a motor vehicle that can be switched on to maintain a selected constant speed without the use of the accelerator."
"Auto Pilot: a device for keeping an aircraft or other vehicle on a set course without the intervention of the pilot."
"Cruise Control: an electronic device in a motor vehicle that can be switched on to maintain a selected constant speed without the use of the accelerator."
