Giovanni Circella, director of 3 Revolutions Future Mobility Program at the University of California at Davis, has been studying how the pandemic has affected mobility and says the widespread adoption of remote work has enabled greater flexibility to travel — but not for everyone. “It’s true mostly for higher-income individuals and white-collar workers,” he says, noting that the option of remote work is far less prevalent among lower-income and minority employees, who are also more likely to be essential workers.
