Option (1) is correct. The size of the motorcycle makes it difficult for the vehicle’s driver to judge its speed.
Further Explanation:
In order to judge the speed of a vehicle, the observer keeps an observation on the rate of changing size of the vehicle. If a body is moving at a higher speed, it will cover the larger distance in small time as compared to the body which is moving at a slower speed.
For the large sized vehicles like trucks, buses etc, it is easy to observe the rate of their increasing size as they approach closer and this makes it easy to judge their speed.
But in case of a motor, it is already small in size and because of this, it appears much smaller when it is at a larger distance and the other vehicle’s driver find it difficult to observe the change in the size of the motorcycle with time.
This makes it difficult for the vehicle driver to judge the distance covered by the motorcycle in the particular time and he/she is not able to judge the speed of the vehicle.
Thus, option (1) is correct. The size of the motorcycle makes it difficult for the vehicle’s driver to judge its speed.
