The ferry is typically much more cramped than the road. Cars, bikes, motorbikes, trucks, tractors, diggers all have to be able to get on board without interfering with each other and without trapping anyone in their vehicles. Even with a willing and cooperative population this gets occasionally difficult, especially when tourists or other people who have never travelled on the ferry before are involved. > Without crunching the numbers, it seems possible that an autonomous ferry could be made cheaper than what an equal distance of road on land. The existing ferry is already considerably cheaper than a road bridge would be. It seems to me that an autonomous ferry would merely shift the work to development and maintenance of the system and add risk.
