It is a race car that is road legal, we were in 4 point Williams harnesses, the only trauma suffered was a fractured rib from the force on impact smacking body into carbon seat. I can only say that in this type of car it is naive to suggest that roll cages are dangerous when you realise that in the case of a roll over at any speed the head would be the highest structure before the body tub that would take any weight. There are no A Pillars, the screen collapses when you lean on it...The bars are there to protect you, there is a head rest on the rear cage at head height, then the front cage comes around the door frames and attaches to bars in the footwell, which in turn are connected to bars in the sills. Which are crucial in a side impact as the chassis is only a foot wide in the middle section of the car, and also they prevent the tyre and suspension from collapsing into the driver/passengers ankles. I would not want to drive this car without a roll cage, it is VERY simple. It is far more dangerous to drive without one, ie, you will die.
