And people forget how much of a PITA it is to get. Waiting in line for 4 hours to get an ID is something I'll do once a decade for my driver's license because I need it to drive and I drive several hours a day.

For people who don't have car, they may not consider the inconvenience worth it just to have the privilege of waiting a few more hours to vote.

"Motor Voter" laws that allowed people to register to vote while renewing their license were designed to make it harder for the poor to vote by making them go through a different process than drivers. Voter ID requirements took it to the next level by requiring them to ALSO go get a license to vote.
