Do you remember science fiction movies as a child? Do you remember imagining what it would be like if the world was able to advance that far in technology? Well, the advancement of technology is continuously evolving. Cars may not be able to fly yet, however, scientists are growing closer to creating a car that does not require a driver. This driverless car will be a great milestone in the evolution of technology. With driverless cars, a public-transport system could be created around the country, according to the vision of Google cofounder Sergey Brin. According to Brin, people would save money because they would not have to worry about buying a car or spending money on fuel. Since this system would be similar to a taxi system, the cars would only use half the amount of fuel as today's taxis, benefitting the environment. This system would also be more flexible than the bus system. In order for these cars to "see" the road and its obstacles, it must have a lot of sensors. According to paragraph four, one of Google's modified cars uses position estimating sensors on several areas of the car, allowing it to mimic the skill of a human at the wheel. Even today, many cars have antilock breaks. Paragraph five states, "The information from these sensors can cause the car to apply brakes on individual wheels and reduce power from the engine, allowing far better response and control than a human driver could manage alone." This supports the idea that these driverless cars will be "smart" enough to actually drive on their own, and possibly more efficiently than a human driver. Furthermore, the invention of driverless cars will be safer. For example, in the case of a drunk driver, the car will have the most control. There may also be instances in which the car encounters an obstacle that requires human control. Efforts are still being made to find a solution to this problem; paragraph seven states that some cars notify the human by announcing it to the driver, and other cars might have a vibration feature built into the driver's seat. Some might ask, if there is an accident, who is to blame? Well, this would depend on the case. If the accident was caused by a malfunction in the car, then the manufacturer is to blame. If accident is caused when the human is controlling the car, then the human is to blame. Now, if a car was compltely driverless, then that question is much easier to answer. Others may also ask, what will the human do while they wait for their "turn" to drive? According to Dr. Werner HUber, a BMW project manager, "We have to interpret the driving fun in a new way." Entertainment and information systems could be developed to keep the driver awake and entertained. This system may sound distracting, however, it is actually a safety feature because it can be turned off instantly when the driver needs to take the wheel. In conclusion, the evolution of the driverless car would make the roads safer, benefit the environment, and save money for many people. The threat of reckless and drunk drivers would decrease, the air would be cleaner, and car rides could potentially become more fun with the possible entertainment. Several companies, such as Mercedes-Benz, Audi, and Nissan, see the potential in these driverless cars, and have high hopes for the future.
