according to the antiterrorist on youtube if stopped walking on a public street by a cop and asked for personal details you have no obligation to provide the details unless you've been witnessed doing something suspicious by the cop or a third-party reporting to the police. to get out of their clutches when they have insufficient cause to arrest or detain what you say when asked for your name, dob, etc., is, "am I obligated to give you that info." repeat the question until he answers. if the cop says "yes" then you have the right to ask what crime it is you are suspected of perpetrating. if the cop says "no" then you ask "am I being detained." again repeat the question until he answers yes or no. if "no" then you say "in that case I am exercising my right to walk away."

I don't know about driving a car but I would question whether or not the rule that applies to giving personal details when 'randomly' stopped by a cop while driving is actually legally enforceable if you don't hold a drivers licence. is the rule actual law or just a rule you agree to when you sign your application for a licence I wonder?

see his 2 part speech on dealing with the police. he doesn't discuss cars I don't think though.

also very interesting and perhaps relevant to the car scenario is his freemen speech which deals with admiralty law - the law of contracts and basically advises not entering into them and in fact freeing yourself from those you've already agreed to. there are 32 licences you need to undertake 32 different activities in society and since they all say "you must hold a licence in order to undertake such-and-such activity" under good faith you can actually become free of their bounds since he asserts that a legal dictionary will tell you "must" means may and is not mandatory. he asserts there are 12 million laws and most apply to contract law.
