Preparing Cities for Robot Cars
The possibility of self-driving robot cars has often seemed like a futurist's dream, years away from materializing in the real world. Well, the future is apparently now. The California Department of Motor Vehicles began giving permits in April for companies to test truly self-driving cars on public roads. The state also cleared the way for companies to sell or rent out self-driving cars, and for companies to operate driverless taxi services. California, it should be noted, isn't leading the way here. Companies have been testing their vehicles in cities across the country. It's hard to predict when driverless cars will be everywhere on our roads. But however long it takes, the technology has the potential to change our transportation systems and our cities, for better or for worse, depending on how the transformation is regulated.
While much of the debate so far has been focused on the safety of driverless cars (and rightfully so), policymakers also should be talking about how self-driving vehicles can help reduce traffic jams, cut emissions (排放) and offer more convenient, affordable mobility options. The arrival of driverless vehicles is a chance to make sure that those vehicles are environmentally friendly and more shared.
Do we want to copy—or even worsen—the traffic of today with driverless cars? Imagine a future where most adults own individual self-driving vehicles. They tolerate long, slow journeys to and from work on packed highways because they can work, entertain themselves or sleep on the ride, which encourages urban spread. They take their driverless car to an appointment and set the empty vehicle to circle the building to avoid paying for parking. Instead of walking a few blocks to pick up a child or the dry cleaning, they send the self-driving minibus. The convenience even leads fewer people to take public transport—an unwelcome side effect researchers have already found in ride-hailing (叫车) services.
A study from the University of California at Davis suggested that replacing petrol-powered private cars worldwide with electric, self-driving and shared systems could reduce carbon emissions from transportation 80% and cut the cost of transportation infrastructure (基础设施) and operations 40% by 2050. Fewer emissions and cheaper travel sound pretty appealing. The first commercially available driverless cars will almost certainly be fielded by ride-hailing services, considering the cost of self-driving technology as well as liability and maintenance issues (责任与维护问题). But driverless car ownership could increase as the prices drop and more people become comfortable with the technology.
Policymakers should start thinking now about how to make sure the appearance of driverless vehicles doesn't extend the worst aspects of the car-controlled transportation system we have today. The coming technological advancement presents a chance for cities and states to develop transportation systems designed to move more people, and more affordably. The car of the future is coming. We just have to plan for it.
Memorandum(备忘录) To: Members of all departments From: Annette Derringer Subject: Year-end party Date: November 26 |
This is just a quick note to let you all know the arrangements for next month's year-end party. As you know, the party will be held at the Green Vale Country Club, which we have reserved between 6:00 pm and 10:00 pm on the evening of December 21st. 1 have received replies from almost all of you confirming attendance, but if you have not let me know yet, please do so in the next day or two. Tickets for all employees have been covered by the company. The manager of Green Vale has asked me to explain one or two things to those of you who have not been there before. Basically, there is enough parking space for only 100 vehicles, so he would like to ask those of you planning to drive to try car pool(拼车)as much as possible. Also, the number of lockers available is small, so guests should try to keep belongings to a ,minimum. Thanks in advance, Annette |

Annette, I will be able to attend the year-end party at the Green Vale Country Club on December 21st although I do not think I will be able to arrive before 7:30. I was wondering if it would also be possible to bring a couple of guests. I know it is a bit of a last-minute request, but my brother and his wife are planning to visit us at that time, and they would love to see the Green Vale. If it is not a problem, then could you let me know how much I should pay for their tickets? Also, assuming this is OK, we are planning to drive down in a single car to reduce the need for paring and also to allow us to keep our belongings in the ear. I will have a couple of days off before the party, and I will not be in my office December 17th, so could you get back to me before then? Thanks a lot, Kyle |
