Do you mean that ' who' is the object of 'drive'?
Actually, what I try to say is ' who will/should drive the car '
In the sentence:
- I don't know who to drive in my car.
"who" refers to the person to be driven in the speaker's car, and is therefore the object of "to drive," just as "John" is the object of "will drive" in the sentence below:
- I just decided I will drive John in my car.
I don't know who to use the car.
Is this sentence correct?
No, that sentence is not correct.
