Routine communication between cars and their drivers is via red lights and bleeps, but there is much room for improvement here. And so, mobility also involves human behaviour and experience. To take some examples, what do we judge to be driving safely/unsafely, fast, too slowly, aggressively, considerately? Looking ahead, will we be able to select the style of driving for our automatic pilot for a journey from A to B? How will road users or pedestrians react to an automated vehicle without a driver? Issues in this area cover: human machine interaction, user behavior, acceptance and mandatory driving skills.
