text: One major aspect of the driverless cars would be the increased advanced technology. This technology will be able to mimic a human driver. Sensors will play a big role in this, and Google's Toyota Prius includes sensors on the left rear wheel, on the roof, radar sensors, an inertial motion sensor, a video camera on the rearview mirror, and a GPS receiver. Also, a spinning sensor on the roof of the car allows laser beams to create a 3-D model of the car's surroundings, which will enable the car to have more control.
