text: Other than these cars being unsafe, what most people seem to not realize is that these cars are going to probably cost them an arm and a leg. Seeing as how these smarter cars are suppose to be smarter and more high tech. Which leads to the next question, what makes a "smarter car" smarter? Well according to the passage Google had modified a car to use position estimating sensors on a left rear whieel, a rotating sensor on the roof, a video camera mounted near the rearview mirror, four automotive radar sensors, a gps receiver, an intertial motion sensor, and a dubbed LIDAR, not including the things inside the car. This all sounds like materials that cost quite a bit of cash and as time progresses and technology improves, so will the sensors and as things get better, the preformence will go up but so will the value, making the car more expensive to make.
