<p>So first off, I feel I should specify I am a beginner at Chinese. In my Chinese class, we were asked to write down a progressive question, using the 在...(呢) format. My question was, 你们没在去吗？ which I interpreted as, "aren't you going?". Another student asked a similar question, with the verb 回来. My teacher said that in Chinese, 去 and 回来 are not used with 在 to become progressive. Why are these verbs exceptions and what other verb have the same exception?</p>

Next time you ask your teacher if this is right: 「我在去/回北京的路上。 (I'm on my way to/back to Beijing.) 」, then watch how your teacher responses :)

From what I remember, she said that you could use it when a specific location is involved, but if you just try to say something like, 他正在去呢， that isn't right.

我在路上 -> 我在(回北京的)路上 -- " 回北京的" is the adjective phrase for 路

@N.D.H, I can't answer that because in Cantonese, 去(go) and 回来(come back) can become progressive by adding an aspect marker 緊 to indicate ongoing action. For example: 去(go) --> 去緊(going) ; 返來(come back) -->返緊來(coming back). But I don't know why it is wrong in Mandarin.

I'm not good at grammar, but I can offer a more comfortable sentence to express that you're on the way to somewhere. 「我正在去呢」sounds weird, but if you say「我正准备去呢」, it'll be better. My comprehension is: if you say that 「我正在去呢」 it probably means that you're already on the way (but actually you're not because you're talking to someone maybe in your house or what).

The answer is "habit".  
Because we don't write or talk in that way.

For example, both 肥 and 胖 mean "fat".  
We call a fat person as 胖子.  
肥子 is not usual because we don't have the habit.

He is going to school.  
We translate it into 他在去學校的途中.  
We don't have the habit to say 他在去學校.

That fat guy is going to school.  
那胖子在去學校的路上。  
??? 那肥子在去學校。 ???

Besides 去 and 來, 返, 歸, 往 and 到 are also included.  
These verbs are used together with something like "on the way (途中／路上)" to express the progressive tense.

回 is acceptable. For instance,  
Q: "他有沒有回電話？" (Did he call back?)  
A: "他正在回。" (He is calling back.)
