Biden was promoting the sale of all-electric vehicles as motorists are facing sharply higher gasoline prices to fuel the cars they almost uniformly drive now.

Biden, out to highlight provisions of the trillion-dollar infrastructure package he championed and signed into law on Monday, visited an electric vehicle assembly plant at General Motors, the biggest U.S. carmaker in terms of light vehicle sales, that says it plans to go all-electric by 2035.

The president’s infrastructure package calls for construction of $7.5 billion worth of electric vehicle charging stations across the country — perhaps a half-million chargers — but Americans have been slow to embrace the purchase of electric vehicles. Last year, only 1.7% of vehicles sold in the U.S. were battery-powered, one-third of the Chinese market, and far behind world-leading Norway, where nearly three-fourths of vehicles sold are plug-in.
