Surely it would be easier to make public transportation more accessible in a non-car oriented city than making driverless cars, which then have large amounts of continuous infrastructure costs, health care costs from less exercise, social costs, and also the fact its still not known if this is even entirely possible. As a thought experiment, we have no cars other than emergency vehicles and some commercial vehicles occasionally. Everyone is able to walk to 90% of destinations, and bike or public transport the last 10%. It would be easier to have people who can't walk well in small electric personal transport devices (wheel chairs, segway, electric bikes, motorized scooters seen at walmart) that if they crash do not pose any threat to anyone. Surely adding wheel chair accessible elevators to train stops for public transit, is easier than building out entire car centris highway infrastructure that requires continuous expensive maintenance. Public transit and walking is already more accessible to the blind than automobiles, that is a nil point.
