Good point. Pure geometry can only handle very low speeds where thereMark-T wrote:

Assuming perfect grip, there will not be a difference.
SaSW, Willem
is virtually zero slip angle. At any speed where there is non-zero
centrifugal force, all tires must run a slip angle, so tire does not
roll on a line perpendicular to its axle. Ackerman angles are
computed for such virtually zero slip angles.
Well, maybe I shouldn't have said ALL wheels run a slip angle. In
certain racing cars that are heavily oversteering, sometimes they run
with the left front wheel actually up in air, so that wheel is doing
virtually nothing, and the geometry is the same as a weird tricycle.
