> Couldn't software gradually increase power to match the grip of the tires and prevent spinning?
Traction prediction is dependent on surface characteristics [1]. You need the vehicle to not only identify the surface, but also predict the vehicle-surface interface and adjust its assumptions as tyre meets road.
It's worth doing. But it's noisy enough that it wouldn't be meaningful for a quoted statistic. (Disclaimer: I've only done this for aircraft on runways, and then only academically.)
Not for take off (or not only for take off), but Audi does this on some of its high end cars (RS 7, etc.) - the vehicle is actively sensing the road, and adjusting for grip, surface, camber and problems (it can actively avoid potholes, for example).
