Driverless cars are coming in the near future. There is debate for whether or not we should allow them on the public roads. People say that driverless cars are perfectly safe and that it can save the amouont of gas used currently by a lot. I think that we should allow driverless cars because they can reduce the amount of driving related accidents, car companies are already planning to release them to public consumers on specific times, and we can reduce the amount of gas used.

Driverless cars can reduce the amount of car accidents and reckless drivers. The driverless cars use sensors so it makes it safe for the drivers. Sensors are already being used on cars, for example, the Toyota Prius uses sensors on the left rear wheel,a rotating sensor on the roof, a video camera mounted near the rearview mirror, and more sensors. The sensors are very advanced so they can detect and respond to danger faster than a human. The sensors can tell the car to apply brakes with a better response time and control than a human could possibly do. Sensors are only getting more advanced so it can only get safer in the future, and it is perfectly safe to use them on driverless cars. Some people may say that it is possible that a sensor fails to work or technology can get messed up, but the chance is rare and it would cause far less car accidents than if a human had full control over the wheel. The smart cars still allow control from the human and the car alerts the human if they and the car are in danger, so if something were to happen, the human could take control and try to stop it. The car still allows people to steer, accelerate, and brake themselves. The Google car announces when the driver should be prepared to take over. GM made driver's seats that vibrate when the vehicle is in danger. Google has been testing driverless cars since 2009. Some companies are also considering using cameras to watch the drivers to make sure that they are alert and paying attention in case something happens where the human would need to take control. There has been over half a million miles on them and no crashes so far so it is perfectly safe to the consumer to use.

The driverless cars can also be used to reduce the amount of gas used today by a lot. Google cofounder, Sergey Brin, said that the cars he foresees would use half the fuel of today's taxis and offer far more flexibility than a bus. People spend a lot of money on gas and it is expensive so if we can reduce that amount by half, then people can use that money they're saving on more important things and can possibly improve our economy.

Companies are already planning for the future. Car companies are making driverless cars and have set dates to when they will be available to consumers. Tesla has projected a 2016 release for a car capable of driving on autopilot 90 percent of the time. Mercedes-Benz, Audi, and Nissan plan for the release of driverless cars by 2020.

Driverless cars are in the future and companies have already planned for them, they are perfectly safe, and they can reduce the amount of spending money on gas. Driverless cars can do way more than they can do bad, and the bad is no worse than what is going on now so we should get ready for driverless cars in the future.
