Why each option
The most probable cause of the flash drive infection is that the public workstation itself was already compromised and transferred malware to the flash drive when it was connected.
War driving is related to finding open Wi-Fi networks and does not involve direct infection of a flash drive merely by its proximity to a hacker while being transported.
The infection was detected on the flash drive after returning home, implying the flash drive brought the infection back, not that it initially infected the public workstation.
Public computers are often poorly maintained and can harbor malware; when Joe connected his flash drive, the infected public workstation likely transferred the virus to his drive.
If the flash drive was already infected by the user's computer, the security software should have detected it before the trip to the public kiosk.
