Insurance companies are probably willing to let it slide if you let someone else who's insured drive your car
Not just probably: I called my insurance to put someone on my insurance, and the customer service rep grilled me about how often they would use it and for what purpose ("Are they using it to commute to work?"), and then strongly recommended I not buy any additional coverage, stating that my existing coverage covered them as well, no problem.
