Good news for all you paranoid people , or if you're not really aware of your rights as a citizen Portland Progressive Examiner: Supreme Court limits vehicle search
it means they cant search your car just because they have arrested you they need a reason ie probable cause
Still can't without probable cause or something in plain sight. I've exercised my right to not be searched numerous times against the GSP(and if you live in GA, you know what they're about), and they let me go without any further questions. It really is all about what you say and how you say it.
