I purchased the Hagerty insurance from my agent that carries all my home and auto insurance policies and it never came up that I had to have a daily driver covered under my name. Course he was well aware that I met that requirement as we've got 2 daily drivers covered.
So sorry, until I read the copy and paste in this thread and then checked my paperwork I wasn't aware or more likely didn't recall I had to have a daily driver covered.

Good luck in the quest.
