Yeah, that's what they want you to think. "We're just here to get this cleared up and get you on your way. Just talk to me, buddy." You are under no obligation

Yeah, that's what they want you to think. "We're just here to get this cleared up and get you on your way. Just talk to me, buddy." You are under no obligation to attest to your innocence. It's not your responsibility to do so. Innocent until proven guilty and all that. You cannot refuse to provide identification (or do a roadside sobriety test). But if there is no probable cause to pursue the matter further, there's only so much they can do without your testimony. There's a lot of damage they can do with your testimony though.
