Fatal mistake: Car sharing economics required fleet utilization above 60%; Maven averaged 45%; COVID reduced utilization to near zero; GM shut down the unit rather than fund losses through pandemic

Documented cause
Maven was GM's internal car sharing venture led by Julia Steyn. The service operated in 17 US cities with GM's fleet assets. Fleet utilization averaged 45% vs. the 60% breakeven threshold. COVID-19 eliminated utilization. GM announced Maven's closure in April 2020.
Lesson
“Car sharing ventures must achieve 60%+ utilization in the anchor city before expanding fleet — Maven proved that even GM's capital cannot fix negative unit economics at 45% utilization.”
