This isn't directly related to any other post, but I'd like to point out that, according to "The National Driver Registry Act of 1982":
"There shall be no access to information in the Register under this paragraph if such information was entered in the Register more than 3 years before the date of such request, unless such information relates to revocations or suspensions which are still in effect on the date of the request."
Assuming that law hasn't been changed in the mean time, I take it that the FAA would not legally be allowed to use the NDR to verify any expired motor vehicle actions you were involved in more than three years prior to filling out the 8500-8 or MedXPress. They'd no doubt have to use some other more expensive verification mechanism if they had some motivation.
