A deaf person is walking down the street on a new moon day. There are no street lights on, infact no electrical bulb or mercury lamp or sodium lamp or tube light etc is On within the radius of 5 Km.
Suddenly a perfect Black Mercedes(totally black, including the drivers clothes, accessories, tyres, dashboard, bumper, i mean to say totally black) came booming from the opposite end of the street towards the deaf person. The head light of the car is off and the driver blows the horn, which the deaf person cannot hear.
Inspite of that he moves away form the car and saves himself.
Now, the question arises that how did he managed to do that?
