Passage 5
Questions 21 to 25 are based on the following passage.
The appeal of self-driving cars seems obvious: just relax and enjoy the ride. But how will life change when entire communities embrace them? Anew town in Essex is the first in Britain to be built for the revolution. Chelmsford Garden Village, which will grow to about 10,000 homes, is future proofing itself for a world in which driverless cars are the norm.
In the early phases, there will be parking spaces near the houses. However, these will gradually be converted to new uses, such as public gardens, and residents will instead be able to summon driverless vehicles from a car park in the suburbs of town. When they are finished, the cars will return themselves.
Jeremy Potter, city planning manager at Chelmsford city council, said:" If you've only got a certain amount of space，you want to maximize（最大化）it for things that are really useful . A car is only useful for a person when they're using it. The rest of the time, it's just taking up space, on the road or drive, which could be reimagined for trees, play space. "
The planned garden village is near a large park and ride site. "This allows the residential environment to be free of cars, "Potter said. The first phase of the development, with 4,350 homes, will have a railway station and rapid bus service ,and is being designed as a ＂15-minute neighbourhood＂ with amenities（便利设施）in easy walking and cycling distance to cut short car journeys. Building of the next 5,500 homes will begin in the mid-2020s.
Moves are under way to reduce car dependence across the country because of fears that planners are forcing developers to pave over garden space for parking. Research by Create Streets, a social enterprise, found some councils require three parking spaces for a four-bedroom house near a railway station. Others insist on at least two spaces for a property with three or fewer bedrooms.
Nicholas Smith, chairman of the government's Building Better , Building Beautiful commission ,said:" We are forcing people in new developments to take car parking places they increasingly won't want or need. It's ridiculous. It should be for homeowners to decide what is needed, not for artificial parking levels to be imposed.
"Parking places should be removed in the future world of car clubs and easy green transport. It will rarely be necessary for new homes to have permanent parking places in town or city centres, and not more than one or two in suburbs or countryside. "
How does Nicholas Smith feel about parking spaces in city centres ?

A.They are insufficient.

B.They are inaccessible.

C.They are inexpensive.

D.They are unnecessary.
