Roll cage are dangerous on the road if you don't have a helmet. 5pts harnesses can break your neck because the retain you completely in the seat not stock seatbelts. There is no real way to prevent you from being fataly hit in the zed sorry even a top safety pick can't do it ... it will always depend on how the event happens. I'm am not trying to be rude or a **** I'm just saying that these cars are a contraption I love mine but I know that I'm no safer then on a motorcycle ....well almost.
