My cousin’s insurance provider wants me to be insured, even though I don’t drive.

I currently rent an apartment with my cousin. I have a driver's license, but don't own a car and never plan on driving his. He told me yesterday that his insurance provider is asking him to either list me on his insurance or show proof that I'm insured elsewhere. At a crossroads here, I don't want to pay for insurance if I don't drive, but I also don't want to spike his rates. Anything I could do about this situation? We're in Michigan if that helps.
