I have no problem with digitized info on a driver's license. Many states including the one I reside in do so. I do have reservations about the administration of such a program.
The only thing that seems to be new is that States would have to share their database now (?)
I don't see exactly what else is new in this Act.
As a former transportation safety professional, I will attest to the fact that a similar federal program (the Commercial Motor Vehicle Safety Act of 1986) did not work for the first 13 years it was in place. It put great burden on the employer, and even with vigilant checks, there were great anomolies from state to state. Also, it did not remove 'bad' drivers from the road. The national database that would have caught multi state licenses was never implemented, or was ineffectivley administered, again putting the burden on the employer.
Maybe, this is Mr. Bush's was of creating jobs. The local news in Minneapolis had a feature last week on the TSA employees who stand around in airports doing crossword puzzles durring downtime. And there is lots of downtime for them. But hey, they are employed!
