Every culture has a recognized (公认的) point when a child bees an adult, when rules must be followed and tests passed.
In China, although teenagers can get their ID cards at 16, many only see themselves as an adult when they are 18. In the US, where everyone drives, the main step to the freedom of adult life is learning to drive. At 16, American teens take their driving test. When they have their license, they drive into the grown-up world.
“Nobody wants to ride the bus to school,” said Eleanor Fulham, 17. She remembered the pressure, especially from kids from richer families. “It’s like you’re not cool if you don’t have a car,” she said.
According to recent research, 41% of 16 to 19-year-olds in the US own cars, up from 23% in 1985. Although, most of these cars are bought by parents, some teens get part-time jobs to help pay.
Not all families will buy cars for their children. In cities with subways (地铁) and limited parking, some teenagers don’t want them. But in rich suburban (郊区的) areas without subways, and where bicycles are more for fun than transportation, it is strange for a teenager not to have a car.
But police say 16-year-olds have almost three times more accidents than 18 and 19-year-olds. This has made many parents think carefully before letting their kids drive.
Julie Sussman, of Virginia, decided that her son Chad, 15, will wait until he is 17.
Chad said he has accepted his parents’ decision, although it has caused some teasing (奚落) from his friends. “They say that I am unlucky,” he said. “But I’d rather be alive than driving, and I don’t really trust my friends on the road either.”
In China as more families get cars, more 18-year-olds learn to drive. Will this bee a big step to being an adult?
