The total value captured isn't just the initial subscription. The LTV calculation should also incorporate, just off the top of my head: sale of valuable customer data, improved targeting of ads for new cars based on that telemetry, upsells to additional subscription services, increases in subscription price, affiliate commissions from other subscription services that get bundled in, etc.

They don't have these things yet necessarily, but hard not to justify it once Pandora's box is opened.
