One of the safest place for a child is the school since the admin makes sure that all are working together for the welfare of the children. They won't let anything to happen to the children, especially since they are making money from teaching the children. The school would lose most of their income if they would lose one of the children. That would make a bad impression on them and that is something that they don't want to happen. Some school have their own bus service, in which, the children take a free and safe ride. Actually, it is not free since the parents are paying in advance to the school for the school service. The driver of the bus is a fun guy and everybody loves him. At least, that is what most school would love you to think.
However, in this game, things are not like that at all. Here, you would be driving a bus school service and you need to get to the finish line as fast as you can. If you want to get to the next level, you need to get the second place. The game gets more challenging as you make some progress.
