Gig drivers who use their own vehicles to provide transportation and food delivery services face barriers to electric vehicle (EV) adoption including costs, access, and information. To move toward a sustainable transportation future, California is advancing regulations to accelerate electrification of high-mileage vehicles, such as those driven by gig workers for transportation network companies (TNCs) like Uber and Lyft. By 2030, the state is targeting 90% of passenger miles traveled on TNCs to be fueled by electricity. To support this objective, UC Davis researchers developed an online tool to help gig drivers understand their potential cost savings from EVs. This research brief summarizes the findings from that research and provides policy implications.
