The “self-driving” car already exists – at least in part. Features such as adaptive cruise control, assistive lane changing, hands-off driving, self parking are already installed in some production cars. What benefits do users have from these innovations? How have computer systems contributed to these developments? What (IT) challenges did designers face in making these features operational? What further barriers are there to the autonomous car and what role might IT play in their solution? If another topic interests you more, address similar issues, whether environmental management, climate change, public health ….
