Chicago doesn't stripe most of the roads. Most of the roads that have stripes in Chicago are administered by IDOT. Chicago even has this codified in the traffic code; while the rest of the state has "improper lane usage" as a violation, Chicago has "failure to maintain a lane". Even on roads with painted markings they get scraped off by snowplows almost every winter. I'm reasonably sure that's what happened to that gore.
