My opinion: replace all cars with self driving only, then you completely avoid the hard problem of interpreting other human drivers. And you can also let the cars communicate with each other, be centrally controlled and/or have assistance in the roads. Why would anyone want to have a non-self driving car. Maybe hard/unrealistic, but it would be super cool to see this as an experiment in a smaller city center to see what happens. It would bring so much opportunity for optimisations also around traffic flow, parking spaces etc.
im pretty sure the videos that got tesla to pull the beta were videos of tesla almost hitting obstacles/pedestrians not other cars. We also shouldnt pretend that pedestrians dont exist, or are 2nd class to cars. imo pedestrians are 1st class and cars 2nd.
I'd still want my car, and I wouldn't want it just driving in circles for hours. Less spots could be necessary in downtown areas, since a car can drop you off and park a few miles away. car ownership isn't going to disappear with self driving, it may reduce, but plenty of people have use cases that a taxi model isn't great for.
Yeah that's my point! You could calculate the amount of needed cars and have them in circulation, and they could park themselves in some underground garage somewhere when usage is low. It could be just one big fleet of self driving taxis, self-driving Ubers.
