I agree, but my thoughts are more on the 'real world' examples of insurance. Like:
- You have to pay IN ADVANCE for it.
- The more safety items you add to your vehicle, the cheaper your insurance is.
- The faster your vehicle is, the higher your premium.
- The insurance scales with the value of your craft. (Already in game)
- The extra items are insured separately (Already in game).
- Your rates go down the longer you are safe
- You get a 'group discount' on vehicles.

- You get long term insurance rewards.
In my opinion, Insurance should be optional, and you have to 'pay before' or 'pay as you go'...
The only reason I say this, is because if you know you have cash in the bank, and that you are in a situation that you are frustrated with, you can just 'Boost into it' and crash.. (Risk Aggressive)
As the point of the game is supposed to make you go: "Oh my god... I can't afford to do that, run away run away run away" (Risk Averse).
Otherwise, Griefers are gonna run rampant with expendable sidewinders they'll just crash into anyone they see who put 1mil into their shiny new ship. The New Ship owner gets to pay 300k, and the Sidey owner laughs as they kick the 'Free Sidewinder' button.
Just an opinion...
