     Every culture has a recognized point when a child becomes 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 grownup world.

     "Nobody wants to ride the cheese bus to school, " said Eleanor Fulham, 17. She brought the

pressure back to memory, especially for kids from wealthier 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 19yearolds in the US own cars, up from 23% in 1985.

Although, most of these cars are bought by parents, some teens get parttime jobs to help pay.

     Not all families can afford cars for their children. In cities with subways and limited parking, some

teenagers don't want them. But in rich suburban 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 16yearolds have almost three times more accidents than 18 to 19yearolds. This has

made many parents pause before letting their kids drive.

     Julie Sussman, of Virginia, decided that her son Chad, 15, will wait until he is 17 to apply for his

learner's permit.

    Chad said he has accepted his parents' decision, although it has caused some teasing 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 18yearolds learn to drive. Will this become a big step to

becoming an adult?
