Hmmm. I bought a car not all that long ago and the dealer did not submit my name to any agency to determine if I was on any terror watch list. Perhaps this is not being done everywhere?
Any real car dealer did, and likely did so after the sale. Lots of paperwork has to be submitted to local, state and federal authorities with every sale. It’s very tightly regulated in Florida, at any rate.
I bought one less than three weeks ago, but they could very well have made such a call while they were "completing the paperwork", and I wouldn't have a clue.
