Anti-Akermann is an understeer geometry, please note here an important thing here is that once traction is lost, the coefficience of traction is exceeded, then you are into a skid, this is NOT and should never be considered "under steer" as that is a fundamental principal of steering and suspension geometry. Skidding is purely loss of traction, under and over steer is measureable and predictable, skidding is not. Over and under steer HAS to have traction. Even deformation of tyres is not under or oversteer, this can be referred to as "slip angle", fundamentally, the 3 things are very different and have very different physical properties. Please NEVER label them all as the same thing.
Neither of these conforms to a race gokart. On a left corner for example, the inside wheel turns left proptionally to how you turn the steering left. The outside wheel starts turning left, stops, and starts to straighten out as the steering wheel turns left. Its because the steering wheel axis is only a few inches to the trackrods, and the pivots for the trackrod ends are several inches from the axis the wheel turns through.
Beautiful illustration , much time spent on the drawing and the simulation, really good work
100% the best explanation on this field when you said two motorbikes it all clicked
It actually isn't that good of a example if you know how motorcycles turn. They do not stay upright, they lean. So, no. It isn't actually like that.

4:41 Unsprung mass ratio is favourable in Veyron.
I like the comparison between a 2cv and a F1!
Awesome explanation, thanks.
You mentioned @3.17 "more steering angle to outer " what does that mean.
In anti Ackerman steering why the outer wheel has more angle than the inner wheel????
tyre slip angle is higher where there is more load to it hence the outer wheel
That's what the whole video was all about lol

So it's hyper-Ackerman? Is that intentional?
Very Good
