What is Mini Bus? Mini Bus is a small pocket in your phone. You can take the Mini Bus to drive around your city and pick up passengers. Do you want to get away from the busy city life? You can take the Mini Bus to the countryside and sit in the quiet atmosphere. 

You can drive a variety of buses, but you must obey the traffic rules. If you do not drive carefully, you will get into an accident and you will be the one to blame. You will lose your passengers and your money. Do not get caught in an accident in the city, you will become bankrupt.
