Google is helping California drivers shop for car insurance as part of a new service that could foreshadow the Internet company’s latest attempt to shake up a long-established industry. The feature unveiled Thursday compares auto insurance quotes from up to 14 carriers that are participating in the comparisons. The policies can then be bought online or through an agent. Google will receive a cut from the insurance sales. The Mountain View, California, company says the size of the commissions won’t influence how it ranks the price quotes. Google Inc. plans to provide car insurance quotes in other states and sign up more carriers, too. The list of initial participants in California includes MetLife, Mercury Insurance and 21st Century Insurance. Some of the largest auto insurance providers, including State Farm, Allstate, Progressive and Geico, haven’t joined Google’s service. Progressive and Allstate’s esurance.com also provide auto insurance price comparisons. The major auto insurers may be leery of Google, which has been using the power and profits from its dominant Internet search engine and other popular digital services to challenge the status quo in other industries. A Google spokesman said the company has no plans to sell or underwrite insurance.
