It seems like this is only anonymous as far as you trust FasTrak not to keep records. Your transponder will eventually fail to read going through a toll plaza.

It seems like this is only anonymous as far as you trust FasTrak not to keep records. Your transponder will eventually fail to read going through a toll plaza. Then what? I see a couple options: * Resolve the toll evasion by associating your plate with your account, then removing it again (surely they keep records of this...) * Pay the toll evasion fine ($25, apparently this does not increase for repeat offenders). Since the golden gate bridge doesn't have cash toll collectors, I think the no-FasTrak is only an extra dollar. * Get a second, non-anonymous account associated with your plate and leave the transponder at home. I think you can get in trouble if your transponder repeatedly fails to register, though.
