The Knight Bus is quite exciting.

We have to agree, the Knight Bus is a fantastic concept. It’s fantastic that stranded witches and wizards have a mode of transportation, and we adore that they may be transported somewhere secure.
However, Harry’s experience on this bus was chaotic, and we need an explanation. Can’t these men, if they’re supposed to be magical, just magically bind the beds to the floor so they don’t fly around? It appears to be straightforward to accomplish.
