Tell her the truth is, she's safer without the roll bar. On the street a rollover accident is very unlikely unless you really drive with a deathwish. The type of accidents you are likely to have involve spinning out and striking an immovable object or some other form of collision. In these cases, your head is swinging around a lot and a rollbar is just something waiting to bludgeon your skull with blunt force trauma. Roll bars are designed to work on a racetrack in conjunction with a crash helmet and other safety equipment.
Street Cobras had no rollbars. Competition models had only one because while racing, you don't often have a passenger. The modern trend of adding multiple roll bars for passengers' unprotected heads is based on misinformation.
