Without seeing film, I'd have to suppose that - it was a FUCKING ACCIDENT. I'd prefer to attribute to that human dozer-jockey that minimal soup\ufffdon of humanity as would have hit the brake or swerved, had not.. his view been obstructed.
She tripped; he may have seen her fleeing and presumed she made it. Anything else - and especially any attempt to justify the dozer-jock having Intended to run over her! - is pure marlowesque bloody mindlessness. Intent is all - only a marlowe would have relished the chance To Show Her! and then Wave the Flag in 'triumph' of machine-brain over human.
Nintendo couch-potato tactical BS, engaged in by callow 11 yos practising bravado 101-Remedial.
