American drivers spend a lot of time going nowhere, from warming up the engine to sitting in traffic or stuck at a drive-through.
Patricia Weikersheimer of the Argonne National Laboratory said that all those idling cars consume about 3 billion gallons of fuel annually.
“And that produces about 30 million tons of CO2,” she said.
But that pollution can be reduced.
