Documented cause
Halo, a Las Vegas-based startup that remotely piloted rental cars to customers using teleoperators, raised $24M from investors and launched operations at Las Vegas airport in 2021. The company partnered with Enterprise Rent-A-Car but could not achieve the cost efficiency needed — each teleoperator could only manage one vehicle at a time, making the model no cheaper than human delivery. Halo shut down in late 2023 after Enterprise declined to extend the partnership.
Lesson
“Teleoperation models need 10:1 or better vehicle-to-operator ratios to undercut traditional delivery costs.”
