$17.4 billion for REal ID; $93 so I can drive.

$17.4 billion is an estimate for Real ID from CAGW (Citizens Against Governemnt Waste). OF COURSE such an organizaton would look at Real ID. Here's what they say:

In October 2005, CAGW released Real ID: Big Brother Could Cost Big Money, which concluded that implementing RFID technology on a national scale could cost $17.4 billion and could push the cost of a drivers' license from $10 to $25 to $93.

Please note that a family with three kids would be paying 5 * $93 or $465 every few years for the right to fly. Hope somebody raises the minimum wage to cover this!
