Oh there are plenty of places that detail voter ID laws disproportional impact on POC, including as
@BlueTX mentioned multiple court cases, aclu just happened to have some of the most easily available figures. Are you disputing their data eg for instance the “up to 25% of African-American citizens of voting age lack government-issued photo ID, compared to only 8% of whites”
Most of the people I know would have the necessary paperwork too but not only do I live in California where we have made a lot of efforts to make votong easier for everyone but most of the people I know have a car - that doesn’t mean I think that the same conditions apply to everyone. As you yourself point out elderly rural people, particularly the poor, would be far less likely to have access to that form of ID.
I don’t recall requiring an ID to vote when I lived in the UK in the 90s and yet despite that it was generally considered a civilized democracy at that time.
Fwiw I don’t have a great issue with voter ID as a concept although I think the ”voter fraud” issue is small to non existent. The issue I have is that some states have clearly been using it to exclude certain segments of the populous from exercising their constitutional right to vote.
