December Mandates Flip Car Markets

Automakers concentrate registrations in December to meet zero‑emission vehicle (ZEV) mandates, creating a predictable monthly spike that can push battery‑electric vehicles from minority share to market lead within weeks. That timing effect means small shifts in regulation or compliance deadlines can trigger rapid, public‑facing tipping points in vehicle fleets and downstream demands on charging, grid and servicing infrastructure. — Mandate timing isn't just administrative detail — it can accelerate market tipping points with wide economic, infrastructure and industrial‑security consequences.
