Might as well compare the prices of apples and oranges and vacuums and space stations.
These comments could be quoting liability only insurance or comprehensive/collision for a kia or comprehensive/collision with bodily injury for a rivian R1S. The insured amount would differ by hundreds of thousands of dollars.
For reference, I have only ever paid for maximum liability only insurance including uninsured/underinsured coverage ($500k/$250k), but not bodily injury, and my premium for 10k miles per year is less than $50 per month. Used to be less than $40 per month before 2022.
