Well another thing is, in this country, nobody has the right to force you to speak or respond. No police officer, no judge, no soldier, and definitely no civilian who got their drivers license from 7 Eleven. You have the right to remain silent, and it does not mean admission of guilt in any way. This has the importance and actual seriousness of a 13 year old kid calling shotgun before entering a vehicle in the judge's eyes I am sure.
