Ah yes, I see how you can read it either way. Even at $10 a ride under the same assumptions that seems light as I assume something like this would cost 100's of millions upfront and then fairly decent running costs.

So VERY guess work but if it was 10x under the same generous assumptions this is ~$45mil/year revenue

What are cost... - $15m for 5% interest on $300m debt? - $15m for running cost and maintenance?

Then a $15m buffer, would not be a margin bad margin for infrastructure if he can start building a bunch of these. Maybe cheaper rides to grow the concept..
