DMVs are designed to serve people with cars first and foremost, my fellow racist.
Not long ago (3 years ago), a terrible series of tornadoes knocked out power all over my area for several days. It was so bad that a lot of people scheduled vacations out of town until power was restored.
During that time, the police issued a curfew. Anyone caught driving on the roads after 10:00PM would be arrested, unless they could provide proof that they were either heading directly to or returning home from work. Which obviously required people to have a radio, and to listen to it, right?
Again, racist, those people in the places where the DMVs were closed had over 200 days per year to get registered to vote.
Face it. Those people who weren't registered were not interested in voting, and were probably too fucking stupid to form a rationale for their vote anyway.
