You hit the head - so or so - without a full cage.
The funny part is, that the guys with these high (ugly) roll bar hoops do NOT strap them in the car.
What I mean strap down, not just have the harness lay on you. As long you can move forward, the same movement will be vertical in a roll accident.
BTW, this is how it looks like when you roll and land upside down off-road. Yep, the 3 inches made a big difference.>>>>
