One Car Challenge
Wednesday 5th August, 2026
LA Metro launched the One Car Challenge, offering Los Angeles residents up to US$600 to leave their car parked at home for five weeks. Participants had to switch to public transport, cycling, walking or car-sharing, with GoCarma tracking mileage to verify the change. The simple cash-for-better-habits hook turned an everyday transport problem into a newsworthy public challenge.
Why it worked: It offered a clear, time-boxed $600 incentive with third‑party odometer verification, turning routine behavior change into a measurable public experiment.
The lesson: Consider a limited-time cash bounty with simple third‑party proof to test a common habit and publish the before‑after results.
