Car insurance companies really hate teen drivers getting added to the policy, here's how bad:

In California, the average policy goes up 88.57 percent.

 That's 14th in the country with New Hampshire leading the increase of 114.92 percent when adding a teen driver.

 In Hawaii where state laws limit an insurance company from considering age and gender, the increase is only 16.83 percent.
