Learn English – What’s the most commonly used opposite of “I’m happy for you”

This expression by nature is very personal, so you'd never see a "formal" version of this expression. This is a light-hearted way to ask what someone's hopes and dreams are. It is about as polite as you can be for this sort of question. Asking someone what their passion is, for instance, might demand a serious response whereas "What floats your boat?" is flexible and allows a non-serious answer, making it all the more polite to use than an alternative.

Though that said, here are a couple alternatives: "What drives you?" "What's your passion?" "What do you do for a living?" (not precisely the same thing, but you might get an equally in-depth answer)

You can say:

I take too much coffee

and

She takes too much time

However the expression: take car is really rare and as Mitch correctly pointed out it is not idiomatic. Native speakers would not normally say this. I fail to see how "car" could be interpreted as an abstract noun as one Chinese teacher suggested. You can however say

Take the car out for a drive."

This is easily understood and does not sound odd at all. Taking too much the car out for a drive sounds stilted; personally, I would never use it. If the speaker (or school text book in this case) wishes to communicate the opinion that the frequency in which cars are used is toxic for our health then something along the lines of

Because they think taking the car too often is bad/harmful for the environment.

is I believe, more natural sounding.
