Are you going anywhere?

Is not a mistake; it’s merely redundant. / // and not even correct. (I didn’t mean to mean incorrect if that’s the correct word or not)? Do teachers say, ‘where are you going’ or other “what you are looking for”, but take their advice with a grain of salt?

But you can’t use the naked “Where are you coming?” Where are you coming from here are some suggestions on

“Indicating direction with from”.

What position are you traveling from in English with adverbs whither and whence?

Where got I? What’s

where are yu going and how do

you come from? Why

are you there? What

were handy additions to the vocabulary, but unfortunately they are now obsolete? You can hardly use them without sounding strange, ironic, or

supercilious.

When the word where refers to a destination, you usually don’t use the preposition “to” as it’s redundant. Why do people use this preposition?

From where are you coming from?

The sentence is highly grammatical. The author is absolutely right about it. When “where” refers to a point of origin, the preposition “from” is required (The Free Dictionary,

pp. 44-48).
