How, exactly, do you propose to do that?
Require tests of one's ability to actually maneuver the car skillfully and to perform various emergency maneuvers in order to obtain a license, instead of the test being little more than memorizing traffic signs and rules. When about 50% to 75% of all applicants fail and must re-take the test, it is comprehensive enough. Require all retirees to re-take this test every two years in order to obtain a license. Treat "failure to yield" and "following too closely" as automatic fails of the test, and treat these violations as nearly as serious as DUI for licensed drivers on public roads. Stop worrying so damned much about speeding since it rarely causes accidents, and start telling cops to ticket slow drivers because they actually do create hazards for others.
We certainly can do this, but you can see there is no political will to carry it out despite all the "driving is a privilege, not a right" mantras you might hear from the states. The states themselves would receive far less in ticket revenues if poor drivers were kept off the roads, so again they have a disincentive.
