Cities keep on inexplicably designing these cool pedestrian only areas for the able bodied and young. There are people who can only travel limited distances, so if you set the beach front back half a mile, you've now cut it off from many older and disabled people.
What I am saying is: For the physically young and able, vehicle-less areas as great, for the elderly and or disabled, vehicles are an absolute lifeline to be able to gain access to things.
For a specific example, where I grew up the shops were pedestrianized (think outdoor mall), my mom had a stroke and struggles to walk, but can drive. The distance from a car door to a shop is a good ten minutes, so she simply doesn't go there. She goes to out-of-town supermarkets with disabled bays right near the entrance.
If the utopia this article wants comes to pass you have to design it with disabled access in mind. "Walk ten+ minutes" is a non-starter.
