text: Cars that can drive themselves need millions of censors just to stay on the road let alone the lane. In paragraph 4 the prompt talks about the cars using LIDAR which is a device that projects a laser and spins on top of the car. Every rotation showing the computer the cars surroundings. While on the road however the LIDAR could spin around and before it get around again an object could have found its way to being in the path of the car giving the car, depending on its speed, hardly any or no time to react. Other sensors could go bad or just the slightest miscalculation or glitch in anything could spell disaster for the car and its passenger(s). These cars should not be developed given today's unreliable technology.
