The 1886 Benz 3 wheeler had a rack and pinion.
I have a nice Franklin mint model or the 1886 Benz with a functional rack and pinion.
Most cars of the era of the picture (probably 1930s) used worm an sector, with a center link to an idler arm. The center link would be stable with the car body and it would only require two linked arms to operate the skirts. Some cars of the era had lights that were connected to the steering so they would point in the direction the wheels were turning.
