which = book
"What" is one of the most over-used words in the English language. It can be a pronoun; it can be a determiner; it can stand for "that which"; it can be either reflexive or interrogative; it ask a question; it can supply an answer. It can even (as a recent thread revealed) stand for "what kind of".

"Which" has similar properties, but isn't quite so overused.

In general, the distinction is that "what" asks a question to which the answer is expected to be indefinite, whereas "which" asks a question to which the answer is expected to be definite.

I realise this answer may not help much, but because the word is so overused it's the best I can do right now. If you give us some context, we can be more precise in our answers.

There is no difference in actual meaning between "What time is it?" and "What is the time?".

To ride (in a vehicle) is to be a passenger;
To drive (a vehicle) is to be the driver.

Both words have many other meanings also.
But you couldn't say, "Can you ride me?", could you?
I might if I wanted sex, but not otherwise.

I think what you need to say is "Would you give me a lift?". Idiomatic though it may be, that's how you request for someone to drive you somewhere in a vehicle.

Thank you very much!!!
Hi Rommie,

Can I say "Would you give me a ride?" instead?
