Users get 10-30% back per route automatically. - Most platforms estimate high and keep the rest. Auto-refund changes the trust equation. - Scaling from 3-5B daily refunds in May to 12B+ now tracks real adoption. People use what doesn't rip them off. Over-provision for reliability, refund excess automatically. Simple concept, rare execution. When infrastructure prioritizes user economics over extraction, usage compounds.
