The rest of the quote is "at your bus driver". Most people would agree that the bus driver has a right to do their job without being the victim of verbal abuse, even if they are a public employee. In this case the crime is "verbally abusing the bus driver", and if the contents of that speech include racial slurs then there could be an add-on offense for hate speech.
