资料:Google and Uber have grabbed most of the attention regarding the advent of self-driving cars, but on Sunday, Lyft threw down the ultimate challenge: A majority of autonomous vehicles for Lyft within a mere five years.
   The bold claim was made by Lyft co-founder John Zimmer in a post on Medium outlining his company's vision for the next decade.
  "Within five years a fully autonomous fleet of cars will provide the majority of Lyft rides across the country," said Zimmer, indicating that early versions of such cars have been in operation in San Francisco and Phoenix.
  Usually when tech founders lay out their vision, it’s typical to hear grand claims that almost push the boundaries of believability. That's what tech innovation is about. But in the case of self-driving cars, the situation is a bit more complicated.
  Uber has already begun rolling out self-driving car tests in Pittsburgh and Google is hard at work on the same kind of solution on the West Coast. Therefore, talk of getting self-driving cars on the road is, at this point, less about the technology and more about logistics. We know Google has enough cash to triple down on any initiative it decides to tackle. And as the current ride-sharing leader in the U.S., Uber has enough market share-powered credibility that a future including self-driving Uber cars isn't unrealistic.
  Today there are some internet-based ride sharing system but to overcome the critical mass the system has to be real-time, automated and extremely easy to use.
  However in the case of Lyft, which continues to struggle against Uber (one report claims that Uber has over 80 percent market share in the U.S.), such a short timeline toward rolling out a fleet of self-driving cars seems somewhat ambitious. Nevertheless, Zimmer continues his vision essay with even more bold predictions.
  "By 2025, private car ownership will all but end in major U.S. cities," says Zimmer, a prediction that, if it turns out to be true, would mean it would take just eight years for the majority of the human-driven cars on U.S. roads to disappear. Possible? Sure. Likely? Eight years seems like, once again, a bit of wishful thinking on Zimmer's part.
  Remember, it hasn't even been 10 years since the arrival of the iPhone, and as recent events prove, smartphones are still a category that can yield catastrophic results if not done right. And those are just mobile devices, not vehicles entrusted with transporting and protecting human lives.
  To be fair, Zimmer's essay does offer some facts and figures in an attempt to back up his positions, but much of it doesn't appear to take into account variables such as the heavily embedded interests of automobile companies still relying on consumer auto sales, as well as the many legal and roadway logistics that will need to be addressed in order to bring about this massive transformation in such a short time.
  Oddly, Zimmer's vision does little to address the millions of human jobs that will be lost once self-driving cars displace not only taxi drivers, but truck drivers.
  "We believe that in the first five or more years following the introduction of autonomous vehicles, the need for human drivers will actually increase, not decrease," writes Zimmer. "When autonomous cars can only solve a portion of those trips, more Lyft drivers will be needed to provide service to the growing market of former car owners," writes Zimmer.
  But what about after five years, when autonomous cars can provide full service? What about the human drivers? The pushback from human drivers losing work will likely be another, major ripple in the evolution of self-driving cars, as well as other automated systems entering U.S. society in coming years.
  However, none of these logistical issues diminish Zimmer's ideas. His vision of the future of autonomous vehicles seems quite logical and in step with most who work in and watch the space closely. But the speed bump in accepting his vision wholesale is his ambitious self-driving car timeline in general, and for Lyft in particular.

第7题:

Motor vehicles powered by the internal combustion engines are responsible for over 80 percent of the deadly carbon monoxide as well as the cancer-causing substances in the air. Eighty-nine percent of the vehicles on the road in Massachusetts are privately owned and are often operated with only one person in the car. If people would use public transportation instead of their cars, air pollution levels could be significantly lowered. Thirty percent of the land in downtown Boston is devoted to cars. Where there are garages, there could be gardens. Where there are highways, there should be homes and places to work and play. Studies show that people today show a greater hearing loss with age than ever before. Much of this is due to car-horns, loud engines and general traffic noise.

The cost of a personal car is high to the individual. The average person pays about $2,000 per car per year in gasoline, insurance, taxes, and maintenance. But for society as a whole, personal cars are a luxury we cannot afford. We pay in death from auto accidents, in poor health from air pollution, in loss of hearing from noise pollution, and in the destruction of our cities by the ever-increasing number of highways.

1、It is ____ that are the main cause of the air pollution in Boston.

A、vehicles in general

B、the public transportation systems

C、carbon monoxides

D、personal motor vehicles

2、The writer’s purpose in writing this article is to _____.

A、remind people of the danger of air pollution

B、warn people of the danger of accidents

C、urge people to use private cars as less as possible

D、ask the Boston government to build more homes and gardens

3、According to the last paragraph, ______.

A、the cost of personal cars is high to the individuals but not to the society

B、an average car costs about $2,000 inBoston

C、personal cars are so expensive that most people cannot afford

D、society as a whole suffers much from the ever-increasing number of cars

4、It is implied but not stated that ______.

A、garages, highways and parking areas occupy nearly one third of the total Boston downtown area.

B、because of highways, people in Boston have no more homes and places to live, work and play.

C、C garages have replaced most of the gardens in Boston

D、Boston is the most seriously polluted city in the U.S.

第8题:

3 Damian is the finance director of Linden Limited, a medium sized, unquoted, UK trading company, with a 31 July

year end. Damian personally owns 10% of the ordinary issued share capital of Linden Limited, for which he paid

£10,000 in June 1998. He estimates that the current market value of Linden Limited is £9 million and that the

company will make taxable profits of £1·4 million in the forthcoming year to 31 July 2007.

(a) Damian believes that Linden Limited should conduct its activities in a socially responsible manner and to this

end has proposed that in future all cars purchased by the company should be low emission vehicles. The sales

director has stated that several of his staff, who are the main recipients of company cars, other than the directors,

are extremely unhappy with this proposal, perceiving it as downgrading their value and status.

The cars currently provided to the sales staff have a list price of £19,600, on which Linden Limited receives a

bulk purchase discount of 6% from the dealer, and a CO2 emission rate of 168 grams/kilometre. The company

pays for up to £400 of accessories, of the salesmen’s own choice to be fitted to the cars and all of the running

costs, including private petrol. The cars are replaced every three years and the ‘old’ cars are sold at auction,

because they are high mileage vehicles.

The low emission cars it is proposed to purchase will have the same list price as the current cars, but the dealer

is only prepared to offer a bulk discount of 5% on these vehicles. Damian does not propose to make any other

changes to Linden Limited’s company car policy or practice.

Required:

(i) Explain the tax consequences of the proposed move to low emission vehicles for both the individual

salesmen and Linden Limited, illustrating your answer by means of relevant calculations of the tax and

national insurance (NIC) savings arising. (9 marks)


正确答案:
(a) (i) Individual salesmen
The taxable benefit is determined by the list price of the vehicle plus the cost of the accessories (£20,000) and the CO2
emission rate. The current vehicles have a CO2 emission rate of 168 grams/kilometre, so the benefit will be calculated
at the rate of 20% ((168 – 140)/5 + 15), resulting in a total annual car and car fuel benefit charge of £6,880 (20,000
x 20% + 14,400 x 20%). The low emission vehicles will be chargeable at the basic percentage rate of 15% resulting
in a total annual car and fuel benefit charge of £5,160 (20,000 x 15% + 14,400 x 15%). The salesmen will thus
make an annual income tax saving at their marginal rate of tax, i.e. £378 (1,720 x 22%) if they are basic rate taxpayers
and £688 (1,720 x 40%) if they are higher rate taxpayers.
Linden Limited
The current vehicles will be classed as ‘expensive’ cars based on the discounted list price plus the cost of the accessories
of £18,824 (19,600 x 94% + 400). The annual writing down allowances will thus be restricted to £3,000 throughout
the period of ownership, but there will be no restriction of the balancing allowance available on disposal. The low
emission vehicles will be eligible for a 100% first year allowance of £19,020 (19,600 x 95% + 400), but there will
also be a balancing charge on disposal equivalent to the sales proceeds. Therefore, the total of the allowances available
over the life of the cars will be effectively the same in both cases. As a single company with taxable profits of
£1·4 million, Linden Limited will pay corporation tax at the small companies marginal rate of 32·75% in the year to
31 July 2007, giving a tax benefit in that year of £5,247 for each low emission car purchased ((19,020 – 3,000) x
32·75%).
The company will also make an annual saving in terms of the Class 1A national insurance contributions payable on the
salesmen’s benefits of £220 ((6,880 – 5,160) x 12·8%). But, as these Class 1A contributions are deductible for
corporation tax, the net saving will only be £205 (220 x (100 – 32·75)%).
As the VAT liability payable on the provision of private fuel is based on engine capacity (not the CO2 emission rate) this
will not necessarily be affected.
