What is the ruling on compelling children to run all errands because the father refuses to provide a driver, despite being well-off?

A father must provide for his wife and young children who have no wealth. The legally obligatory maintenance is limited to basic needs only and does not include providing a driver for the wife or children, or buying a car for the son or replacing it with a better one. The son must treat his father kindly and not dispraise him, and he will be rewarded for transporting his family members and fulfilling their needs.
