ABS still puts rubber down and you just use the same model car and weight to calibrate the fiction coefficient and deceleration.

They have calibration tables for all models of car and only when lawyers get uppity about surface friction do they have to do a reconstruction test. Quite often they do a known police car test at the time and that gets used to get the friction coefficient and then that's linked to the car model.
