Answer – (D) 90%
When driving we get “90%” of the information we need from our eyes. When we sit behind the steering wheel of our car the first thing we do is look around to find any obstacles stopping us from moving ahead. This simple act of gathering information is done solely by our eyes as we cannot feel or touch them while sitting inside.
Similarly, we see road curves, traffic lights, and signals to make the decision whether to keep driving or stop. We also look out for other vehicles on the road to maintain a safe distance and avoid any type of collision that can damage our car. These are the bare minimum requirements of driving and our eyes do the task of gathering the information needed.
Besides that, we also use our eyes to read maps and navigate through the turns. Most of the time, we judge how fast the car is going by seeing our surroundings or looking at the odometer. If we just close our eyes when sitting in the driving seat, we will not be able to do even the simplest of tasks like putting the car keys in the correct location and starting the engine.
Now, looking at the remaining 10% of the information we need while driving, we will see that it comes from our remaining senses and instruments installed inside the cars such as the horn sound or the feel of the steering wheel. Nevertheless, most of the info we need for safe driving comes from our eyes.
