not even markings on the pillars - bland they blend in to the scenery. if a car hits a pillar it could mean disaster. built on a budget: some floor joists are held on the side of pillars instead of on the pillar by "extension" - not exactly redundant

lights don't highlight anything they are set to provide a blanket blend-in cover
