Car race trend is related with safety problems

Because China has higher inflation than America, this oddly implies a steady depreciation in the yuan’s nominal rate against the dollar of 10% over the next five years. The forecast surplus would be smaller if you instead assume that the yuan’s nominal exchange rate will stay constant.
The men who race the cars are generally small, with a tight, nervous look. They range from the early 20s to the middle 40s, and it is usually their nerves that go first.
Fear is the driver's constant companion, and tragedy can be just a step behind. Scarcely a man in the 500 does not carry the scars of ancient crashes. The mark of the plastic surgeon is everywhere, and burned skin is common. Sometimes a driver's scars are invisible, part of his heritage. Two young drivers, Billy Vukovich and Gary Bettenhausen, raced in their first 500 in 1968. Less than 20 years before, their fathers also competed against one another on the Indy track—and died there.
All this the drivers accept. Over the years, they have learned to trust their own techniques, reflexes, and courage. They depend, too, on a trusted servant—scientific engineering. Though they may not have had a great deal of schooling (an exception is New Zealand's Bruce McLaren, who has an engineering degree), many drivers are gifted mechanics, with a feeling for their engines that amount to kinship.
A few top drivers have become extremely wealthy, with six-figure incomes from prize money, endorsements, and jobs with auto-product manufacturers. Some have businesses of their own. McLaren designs racing chassis . Dan Gurney's California factory manufactured the chassis of three of the first four ears in the 1968 Indy 500, including his own second place car.
Yet money is not the only reason why men race cars. Perhaps it isn't even the major reason. Three-time Indy winner(1961, 1964, 1967) A. J. Foyt, for example, can frequently be found competing on dirty tracks in minor-league races, where money, crowds and safety features are limited, and only the danger is not. Why does he do it? Sometimes Foyt answers, "It's in my blood. " Other times he says, "It's good practice. " Now and then he replies, "Don't ask dumb questions. "
Car races has already become a fashion for some young rich second generation. While in mining machinery industry, it seems not that thing. Each processing in production, the workers should pay more attention to safety. Good quality of car or all produced in that way.
