The first is price. Most electric vehicles are still relatively expensive, giving some potential buyers sticker shock, even after federal subsidies. As technology and production methods improve, prices will come down. Along with allowing for more plug-in hybrids, the United States needs to avoid an escalating trade war that could keep prices high.
China, which makes most of the world's electric vehicles, has been able to make them cheaper and sell them at lower prices, thanks partly to generous government support and lower labor costs. But even China is seeing a market slowdown, raising concerns in the United States, Europe and Canada that it is preparing to dump its overproduction of vehicles overseas at lower prices, further undercutting domestic carmakers.
Canada recently announced it was following the United States in imposing a 100 percent tariff on Chinese EV imports starting Oct. 1. The European Union earlier imposed tariffs of as much as 38 percent, but lower for Tesla and Chinese carmakers in joint ventures with E.U. companies. China has criticized these moves as trade protectionism and threatened to retaliate. A green-tech trade conflict that could complicate sales of finished cars as well as critical materials and parts would do neither consumers nor the environment any good.
In the United States, the other main problem with EVs is concern over the availability of public charging stations. That's a real worry, especially for urban car-buyers who might not have a garage or private parking space. The Biden administration has tried to ramp up construction of public charging stations. But so far, the effort is falling short.
Encouragingly, Detroit automakers have announced plans to make their charging stations compatible with Tesla's. That makes sense, since charging an EV should be as easy as pulling into a gas station to fill up the tank - easier, even, as chargers should be in places drivers are already going, such as parking lots. Yet the industry still depends on a massive federally backed build-out of charging infrastructure that is only just accelerating.
