This just occurred to me:
For the people arguing that the 5% deductible should be paid up front, it doesn't change much. Consider the following:
* You buy your ship, and pay your 5% deductible up front because the insurance company doesn't trust you (think deposit).
* You crash.
* You get your ship back, but you've lost your deposit. The insurance company trusts you even less.
Will they let you take off without another deposit?
If no: Then the system is exactly the same as right now, but ships cost more up front. (Though I suppose you could sell your ship if you can't pay the deposit -- since they won't let you take off with it anyways)
If yes: Then the system is exactly the same as right now, except ships cost more up front and you've got one mulligan. After that, you need to reserve money for deductibles again.
So things wouldn't be very different (reverting quickly to the way things are now), except we've removed the option for players to take calculated risks to progress faster.
