DESCRIPTION:European public policies incentivize the deployment of fast-cha
 rging (DC) infrastructure based on the premise that local EV adoption drive
 s public charging demand. We invalidate this assumption using a dual-layer 
 dataset combining a proprietary panel of 15\,314 monthly connector utilizat
 ion observations with exhaustive geo-spatial network data (12\,000 stations
 ) in France. On the demand side\, we document a "Residential Paradox" that 
 creates "Zombie" assets. Using a fixed-effects model on charging sessions\,
  we show that while local wealth positively predicts utilization for AC (sl
 ow) chargers\, it has a null or negative interaction with DC (fast) utiliza
 tion. We attribute this to a structural substitution effect: in wealthier m
 unicipalities\, the prevalence of private parking renders public fast-charg
 ing redundant. On the supply side\, we demonstrate that connection subsidie
 s sustain this misallocation. Rather than correcting for local demand\, mar
 ket actors mitigate risk by minimizing deployment costs via a "Copper Trap.
 " Controlling for population density\, we find that "Speculator" entrants l
 ocate stations significantly closer to grid transformers than service-drive
 n incumbents (p<0.05). A counterfactual analysis estimates that this "grid-
 hugging" strategy generated a subsidy leakage of €48.6 million in avoided
  civil engineering costs—public funds captured as operator margin rather 
 than delivered to users. We conclude that current regulation fosters a doub
 le market failure: it directs capital toward areas where private substituti
 on kills demand\, and incentivizes locations at grid edges where user utili
 ty is minimized\, resulting in a €73 million fleet of socially sub-optima
 l assets.\\n\\nContact: Xavier Chatron-Colliet : xavier.chatron-colliet[at]
