I have been following this discussion as I interact with legislators in
Texas on electronic drivers license bills on the floor here.

Attached is a 2016 report Rep. Goodwin's office shared with me detailing
our state's primary concerns for establishing e-licenses. This is more of a
policy framing, but some of the tech challenges are consistent across
states/the U.S. and have been helpful to my company's work in this space.

Best,
