There is another effect too. The inside tire turns further faster
_before_ the weight transfers. So, that tire grabs more on turn in.
It is easy to think of ackerman as dynamic toe. The toe of the front
tires increases as the wheel turns toward lock. IMHO, running a lot of
static toe out is a hack for not having sufficient ackerman (sufficient
for autocross is probably over 100%). Of course when the rules say you
can't modify the suspension geometry, it is a hack you've gotta deal with.
