Neat little web site but several of the demos are simplified and don't tell the whole story.
For example, the section on Ackerman has a demo based on the way rack and pinion steering works but that is far removed from the way all modern and some vintage kart steering is designed. It makes the assumption that the distance between the spindle arms remains constant and that is not the case when the steering shaft is fitted with a pittman arm with two pickup points for the inboard end of the tie rods. On a rear steer setup with two pickup points on the pittman arm the distance between the spindle arms get shorter the greater the steering input.
Accordingly, a system with spindle arms that are straight back can still have an Ackerman effect although as Andy pointed out up above it may not be true Ackerman so we could call it dynamic progressive toe out and still be talking about the same effect.... tighter turning radius on the inside wheel.
