As an electric car advocate, Chelsea Sexton was notably featured in the documentary film Who Killed the Electric Car? She entered the automotive industry through working with General Motors on their EV1 electric vehicle program. She became deeply involved in bringing together a variety of stakeholders to support the line, from corporate and non-profit entities to policymakers and then drivers themselves. After the EV1 line was closed, she continued her work as an advocate for clean, efficient transportation.
