Back when I was too broke to afford a lawyer, my favorite part of traffic court the couple times I went was all the people video calling in from the local jail who are in jail because they didn't pay tickets they couldn't afford and then inform the court that no they still can't pay them because they are in jail.
For a few years before Illinois did away with cash bail they had a rule you could pay your bail off $5/day by... sitting in jail. So if you sat in jail for a year you might actually save up enough credit to be able to bail out.
