How did the first astronauts get inside?

Depends on your definition for autonomous driving which mainly depends on your ODD but they’re not the only ones. Honda ,Volvo and GM have something. Others (i.e. BMW) have stuff next year but they’re all going with more accurate names. CoPilot, PilotAssist, Super cruise, Traffic Jam Pilot. Makes it clear that these are drive assists, not drive replace.
