I had the same problem, you play the mission and when the dealer stops his car, a yellow arrow is supposed to appear on the road behind him but it doesn't. I have solved it by reducing the graphics settings to a minimum until the resource usage is below the indicated maximum, then I changed the aspect ratio to 4:3. I played the mission, and when the dealer stops his car, a yellow arrow appeared behind me. Moving your car to the yellow arrow will trigger a cut-scene to continue the mission.
