  • Discontinuance Among California’s Electric Vehicle Buyers: Why Are Some Consumers Abandoning Electric Vehicles? [supporting datasets]
    Hardman, Scott
    ORCID ICON IMG
    2021-03-04 | PDF
    For the market introduction of electric vehicles to be successful first-time adopters need to make continual purchases of the vehicles. Discontinuance, the act of abandoning a new technology after once being an adopter, has implications for market growth and could prevent electric vehicles ever reaching 100% market share. In December 2019 we resurv ...
