Actually, I thought it was the "...small cornering radii and at low
speeds the extent of torque redistribution can increase to the
torque split limit of 25/75%" case that he was considering.

Also "On a high-grip surface the torque split limit is reached
at a radius of about 15 meters".

Answering my own question on the speed of the car for the 38/62% case:

Radius = 40m
lateral acceleration = 4 m/s^2
v^2/40 = 4 (lateral acceleration is v^2/R)
v = 12.6 m/s or about 45 km/h or just over 28 mph.

This unfortunately represents just one moment in time
since the paper claims the car is accelerating at 4 m/s^2.
If they maintain constant radius, then lateral acceleration
must be increasing.  If they maintain constant lateral acceleration,
then their radius must be increasing.
