Welcome to the Peoples Republic of California . I wonder what their objection is ? High impact, scratch resistant slightly tinted windows are as safe as OEM . I wouldn't put it on the front windshield , though . Every state has its issues . Here in New Hampshire rust is their biggest issue . Vehicle may be fine mechanically but can't have any rust bigger than a half dollar . don't need insurance either , don't require seat belt use either . Motorcycles riders don't need a helmet , but, bicycle, sled and atv riders need brain buckets . Go figure
