The big disadvantage is that when it fails it's catastrophic. It just shatters. There's no warning. At least with steel it bends before it fails. That's not the case with carbon fiber.
Not much of this comment checks out ?
As far as why fiber is a better choice, the bigger the sub the more people it can carry. the more people it caries the better the company can cover costs. Specially since the sub cost is a one time fixed cost and the supporting costs are recurring variable costs. So it's worth making the vehicle as large as possible. Long term a bigger sub will be a better choice to get to profitability.
It's all a guess on my part.
I mean, a machine would have a hard time to make it come up.
It's pushing on a string... to me, that's just nuts.
Someone has to have a good explanation on how I'm wrong. If not, that makes it even more tragic.
