Imagine being able to get into a car and go somewhere without needing to drive. Crazy right? Wrong. This very well may be our future. Google cofounder Sergey Brian envisions a driverless car public transportation system. The kind of cars that he sees in the future would have the ability to use half the fuel that we use today, and offer more flexability than other transportation systems like the bus. Driverless cars at first read might sounds very dangerous and raise a lot of questions. How safe will it be? How can it sense all the many situations that can occur while driving? and many others. Many companies are beginning to manufacture these computer-driven cars and have run into the same wonderings. At first they believed that they needed to make the roads "smarter" and have them embedded with electrical cables or magnets, but soon realized the cost would not make this worth it. Realizing that now they needed to focus on the cars, they found that they would need a whole bunch of sensors to make it safe enough. As of now cars have sensors that help you park and maneveur in certain ways but not to the extent of driverless. Google has modified the Toyota Prius with the use of sensors on left rear wheel, rotating sensor on the roof, video camera mounted close to the rearview mirror, along with four automative radar sesors, a GPS receiver, and an inertial motion sensor. In this, the most important part is the rotating sensor on the roof, because is uses laser beams to constatnly updating 3-D model of everything around the car. All of these modifications are key for the dirverless car to mimc the skill of a human at the wheel. Today there is no such thing as a completely driverless car since so many factors go into the development. Although in 2013 BMW announced the development of "Traffic Jam Assistant". This car is capable of functions up to 25 mph,but there are sensors on the wheel to make sure the driver keeps ahold of it. None of the cars developed so far are completely driverless, therefore they can steer, accelerate, and brake on their own, but still are manufactured to notify the driver when they need to take over control. Meaning the driver must still stay in high alert. With this, the question has arose of why would people want a car that is only a little driverless? Dr. Werner Huber, a BMW project manager driver says, "the psychological aspects of automation are really a challenge." They have to interpret the driving fun in a different way. Some inquire to bring in entertainment and informations systemns that use heads-up displays. These could be turned off instantly as soon as the driver was in need of taking over. Therefore, the in-car system is actually a safety feature. In many ways the driverless or partial driverless cars have many things to work on and are being improved upon everyday. Some might say it sounds too complicated or dangerous, but when you think about the benefits it is truly worth it. You would be able to save on gas and have a safe easy way to get places you needed to go. This is especially true for those too young to drive on their own. Automakers are actively proceeding in their work to make sure these vehicles are safe and effective. So far, Tesla has projected a 2016 release of a car that is able to drive on autopilot 90 percent of the time. There are also Mercedes-Benz, Audi, and Nissan that are planning on having driverless cars by the year 2020. The road we are headed down with these driverless cars is huge. Not only will it change the way we live and how the roads are run, it could greatly impact the environment and our futures. Being able to get more people where they need to be for less money in better time will be a huge accomplishment. Even though it might still seem very far into the future, it will be here sooner than we think.
