Agree that the graph cannot be a real life depiction. In either case (R to L) or (L to R) the trailing tire would never cross past the line of the steering tire, unless there was a counter steer to the other direction. Think of pulling a trailer, the trailer always goes to the inside of the curve and never outside.
I get the mathematical, but the graph is wrong.
In my earlier post I was wrong as I was assuming the turns on a straight line perpendicular to the x-axis and forgetting there is length to the bicycle.
