Damage-based estimate of 32 km/h was REJECTED (impact unavoidable at 7 m sightline) and constrained-repaired to 23.4 km/h consistent with the 2.6 m skid and the no-contact outcome.

Recomputed from repaired kinematics under the oriented-bounding-envelope model: braked trajectory clears the stopped vehicle's front-right corner by 0.15 m at t≈1.41 s (constant while the pedestrian walks past the stopped car).
