Far from spotlighting the promise of EVs, her public relations misadventure in Georgia involved one of her staff in a gasoline-powered vehicle blocking off a coveted charger in advance of her arrival, leading to frayed tempers and a local EV owner calling the cops. It was an illustration of the challenges drivers could face as governments push the public to embrace plug-in vehicles.

Hyped as technological marvels, EVs are boobytrapped with a host of inconveniences and tradeoffs. By now many people have heard about range anxiety, exploding lithium-ion batteries, and the environmental destruction caused by global mining for battery minerals.

But another wave of challenges is in the offing as the federal government and state officials pump in billions of dollars to build out a massive national infrastructure of charging stations to power the EVs.

The sheer scale of a charging infrastructure means recruiting retailers and businesses to install and maintain chargers that are expected to lose money in the near future, with some likely to be written off as economic losses.

In California, which is slated to ban sales of new gasoline-powered cars in just 12 years, government estimates indicate the state may need to install at least 20 electric chargers for every gas pump now in service to create a reliable, seamless network.

Massive public subsidies will be a crucial part of this effort because private industry is not willing to take the financial risks of betting on an uncertain future. Government subsidies mean complying with recordkeeping and reporting mandates and making sure chargers are online 97% of the time, while bearing the financial risk of vandalism, mechanical malfunctions, daily fluctuations in electricity pricing, and cashflow unpredictability.
