Imagining the future without having to manualy drive cars is amazing but it would also be a big hasle. Having these cars would save lots of money and fuel. There is a lot to do with these special cars. Some of the postive things about having these cars built is the way their sensors, driving and assisting, and laws work. Some of the negative outcomes is that the sensors might not work all the time or the car still needs manual help on some conditions. Brin Can is the man who thought of this whole idea. He works for Google. Brin has a plan to make these cars drive themselves by 2020. He says having these cars made would save on fuel. Americans would only use half the fuel they use now. Also making transportation far more comfortable than a bus or a train. With not having them made Americans would still drive manually like the usual. Without this the people could still drive drunk on off of something and get into far more accidents than these smart cars. These autonomous cars can steer, accelerate and brake all by themselves. Plus it has monitors surrounding the car for any accidents to prevent. Engineers at Berkeley have use something useful. They put this magnet into the car to help it sense postive and negitive polarity in the binary code. There are sensors on the front and end of the car. Google said for the cars to become more smarter the car needs more sensors. Having these would help humans get into far less accidents then they would by themselves. Still not having these with the regular cars humans can see behind the car or around them as easily as if they had sensors. On these smart cars some good ways to alert humans that they need to take control is the windsheild would flash if the driver needed to take control. Also the seatbelt will vibrate if backing into something. It also announces when the driver should take over. Some negitive aspects of having these cars would be that the sensors or the car arent 100% there yet. This anonomous car still needs human help when backing out of a driveway or going around construction. Having to be aware and waiting your turn to take over would get boring. That would be very tiring. Why wouldn't you want these hand free cars? That help you when needed and giving you some free time. With the help of these cars and can prevent 80% of the accidents that happen when a human is either tired, drinking or lost control of the car. This car will be here before you know it. Telsa has projected a 2016 release for a new car. The Nissan, Audi, and Mercedes-Benz will be the new start of this generation. These cars are hoping to be made and drive themselves by 2020.
