Car insurance policies that major insurance companies underwrite tend to be less expensive. Because large insurers write millions of policies each year, they can afford to price their policies more competitively. Additionally, the biggest insurance companies in the U.S. often have more coverage options. If you want to customize your policy with endorsements or need specialty coverage like rideshare insurance, a large provider is more likely to have those policies.
