Cars and motorcycles differ on wheels and over all physics. They move, stop and turn differently. A motorcycle can cover a smaller space while a vehicle covers a big space. Since a motor vehicle is larger, it can carry lots more people, can waste more resources and will isolate the driver from the environment. This isolation is a very common method to obtain road accident. A person in the car is less mindful of his surrounding thus it allows anybody to use his cellular phone while driving, read or eat resulting to more accidents as a result of distracted driving.
