would this pass chassis certification?

I hate to be the spoiler here.....but there is NO PLACE for rear seat passengers once a car is equiped with any type of bar or cage! Do you really wanna risk someone you cared about smashing thier face in one of those bars, in event of a crash? However unlikely a crash may seem to you! Either forget the bar....or lose the rear seat. Sorry, dont mean to spoil your fun, but you wouldnt be very well if someone died of blunt force trauma in your car.
