For driving in India, you need three things: Good horns, good brakes and good luck! Horns are used constantly - every vehicle has a sign on its rear saying "Sound Horn". The reason is to let the driver in front know when you are overtaking him, or want to overtake him, or a myriad other reasons, too. Karim has a choice of horns here. When you get bored with one sound, after hours of monotonous driving, simply flick a switch on the dashboard, and you have a new horn sound.
