There is no question that fewer teenagers are on the roads in the US.

  In 1978, 50% of 16-year-olds had got their first driving licence. In 2008, according to the US Transportation Department, it was just 30%. The number of those aged 19 and under with driving licences has also been declining since 1978, when 11, 989, 000 had licence. In 2010, it was 9, 932, 441, or 4.1% of American drivers.

  In the UK, 683, 273 teenagers have driving licences- just 1.85% of total licence holders, according to Department of Transport figures from September 2010.

  But the decline in the US may have more to do with tougher tests and the introduction of the new rule in many states, which force drivers aged under 16 to be with licensed drivers of 21 years and older when driving.

  In recent years, the annual number of journeys being made by American drivers of all ages has declined clearly for the first time ever. Car use began falling in 2007, when average petrol prices almost doubled to $4.12 a gallon, and the economy became worse.

  But there are signs that it is getting back to normal and American remains a country on wheels. It has a higher number of cars per head of population than any other country in the world.

  “Cars will always be a popular means of transportation in America. You have to take into consideration some places don’t have access to public transportation. Cars are the only way some people can get around,” says Kristin Nevels. This makes driving necessary in some rural states, where about twice as many teenagers are on the road than in big cities.
