 Drivers using the automated FasTrak toll system on roads and
 bridges in California's Bay Area could be vulnerable to fraud,
 according to a computer security firm in Oakland, CA.

 Despite previous reassurances about the security of the system,
 Nate Lawson of Root Labs claims that the unique identity numbers
 used to identify the FasTrak wireless transponders carried in cars
 can be copied or overwritten with relative ease.
