Has driverless cars ever came to your mind before? To think that car companies and Google are working on these futuristic things are mind blowing. In a few years we could be in the future era of cars. Cars like this would change the world. They would use less fuel, help improve safety, and allow the driver to have fun.

First reason driverless cars would help improve our life is they use less fuel. Having to use less fuel would save people big money. The cars would be able to travel more miles per gallon. Since these cars will only need half as much fuel, people could select cars not based on how much gas they use, This would allow customers to choose the car they really want.

Second reason driverless cars would help improve our life is they can decrease the number of car crashes. Inside all these cars are loads of sensors. These sensors help the car stop, slow down, or brake automatically. By having this kind of technology, the car accidents around the country would drop. That also means more people would buy these cars knowing they are safe.

Last reason driverless cars would help improve our life is because they would allow the "driver" to have fun and relax. Some of the manufacturers would put in-car entertainment and information systems in the car. These display systems could turn of instantly in case the driver wanted to take over the car. Drivers in the car could also text if they wanted too. They would not have to worry about hitting someone or something.

Driverless cars would greatly improve our society. They would use less fuel to save us more money, decrease car accidents, and make drivers less bored. It could take many more years for these type of cars to come. They might not even come for another 20 years. When they do, we will all be living in the future era of cars.
