"A homeowners insurance calculator gives you a rough estimate of how much homeowners insurance you need based on several variables such as geographical location, and square footage."
Then you are running the risk of having elevated insurance premiums, should you ever own your own vehicle and attempt to insure it, and this vehicle/policy has a bad/rough insurance record.
A Rough Cost Estimate is an initial estimate that uses prior experience and other non-project data to estimate the cost of a project. It is also called a Rough Order of Magnitude (ROM) estimate, or a Conceptual Estimate. The Rough Cost Estimate is used for project screening, or deciding which among several projects to proceed with.
A quote offered by an insurance company is a rough estimate of the amount you will pay in insurance fees. A quotation is most commonly used in writing to note that someone is speaking.
I estimate six.

No. You need to have an insurable interest in the vehicle. (Rough) Example: If you could be the insured party on any car you didn't own, you could claim that car was written off and get a payout that wasn't due to you. Actually, when I was 18, I was co-insured on a car that was not in my name. Not added to a policy, but my name was actually on the policy with the owner of the car even though my name was not on the title or registration.
A rough estimate
If you purchase your insurance in Croatia then yes I would say so. If you have a policy issued on another continent such as North America then NO. Read your policy, as it will clearly state where you are insured to drive. Driving from USA to Croatia will be rough anyway. Sorry for the sarcasm.
ballpark
A rough estimate is given when the situation does not require the exact numbers to be given.
