Bolt in cage?

sounds like the rulebook is saying a unibody car is not safe with a roll bar welded to sheetmetal. my insurance company for the street said no rollbar - I said jeeps have rollbars! and mine is well padded. Is there any data that on the street with a padded bar and a 5 point harness and no helmet no rollbar is safer. I have seen some bad street car crashes and said looks like they may have lived with a rollbar and seatbelts
