Well, all of these could be the future of driving. There are several companies, for example, Google, working on driverless cars. So far, no Google selfdriven car has got a traffic ticket, but some of them have been in accident when other cars hit them.

These cars are now still in the testing stages. If the tests are successful, these electric, selfdriven cars could be available very soon. But how is it possible for a car to drive itself?Cars already have many features allowing them to take the place of drivers during certain situations. Some features include cars being able to park themselves, or slow down when they notice other cars close by. They can also control the speed if there are dangerous conditions.

Scientists believe that with the help of wireless signals, cameras and GPS, it is possible to create a safe selfdriven car very soon.

The cause of deadly road accidents is usually careless drivers or dangerous conditions. The selfdriven car may be able to stop this. However, some people do not like the idea. American lawyer Whit Drake, for example, doesn't believe these cars are safe. He thinks that technologies can also be mistakes.
