There are YouTube videos documenting these interactions between drivers and checkpoint officers. ("Are you a United States citizen?" "Am I being detained?" repeated over and over.)

Does anyone know how the law applies to cyclists near the border? "Getting out of the vehicle" and "allowing access to the vehicle and contents" are different when the vehicle doesn't have doors, a roof, a trunk.....
