Now Texas feel the heat:

An article in the Brownsville Herald (Texas) by Elizabeth Pierson quotes a spokesperson thus: "[It will] cost the state an estimated $268 million. The money will go toward paying for technology and hiring more than 700 employees to handle the increased traffic."

There's an estimate that an additional three million people (almost double the current number) will need licenses; Texas will no longer be able to accept the Mexican "matricula consular" as proof of identity; and all licenses will expire and require renewal. (One of Texas's current efficiencies is that some licenses never expire.)
