This is my very first post on any forum ever so don't hate me if I messed up where to put it or something (I'm doing my best).... I just want to open a dialogue on the daily driving safety (no helmet) with the hard dog roll bar. I have seen on these forums and also miata forums (wife is a miata fan girl) about how whacking your noodle on a roll bar is a serious concern. I installed the single diagonal hard dog roll bar around 6 months ago and I'm struggling to see how getting your head any where close to hitting they bar is a stretch. The only possibility immediately obvious to me is if the passenger is reclined hard core and you get T boned on the driver's side. If that happens they might hit their head on the diagonal bar, so I put foam on it. The bar is a solid 6 or 7 inches from the back of the seats and even if I take my seat belt off and wiggle about violently I can't get my head near the bar. Is there somthing I'm missing, am I too short (5'9), are a bunch of people who have never even seen the bar in person just making gross assumptions, will I die. I dunno please help.
