I can always become lucid by looking at my hands and rubbing them together and asking myself, " is this a dream?"

In my dream last night, I was driving a car and thought,, wow, I do not remember where I just drove,, and then thought,, oh, I bet this is a dream,, checked my hands and I said,, no, this is real..
The dream continued, and it is way too long to post the whole thing, but I was never aware again that I was dreaming..

Anyone eles missed a dream sign or have it not work?
