I went to a seminar put on by the Seattle Chapter of the National Lawyers Guild. If police stop you outside a car, this is what you should do:

ask: "Am I free to go?" Persist until you get a yes or no
-if yes, leave ASAP
-If no, say this:
"I'd like to speak to a lawyer"
"I don't consent to a search"
"I am exercising my right to remain silent"

You must request a lawyer clearly and directly.
Simply being silent doesn't invoke that right. You have to invoke it directly.
