Carpool (1996)

A man with an important business meeting finds himself needing to take on the carpool for the neighborhood schoolchildren when his wife becomes ill. He stops to buy them doughnuts and things go even more awry when he becomes a robbery victim and get even worse when a desperate man who had been contemplating a bank robbery robs the robbers and takes the man and kids hostage in their van as his truck is blocked by an armored car. As it becomes a comedic chase movie the father discovers that his kids don't really respect him--and react better to the robber. The end result is that everyone gets a lifestyle change, including the original store owner.
