My biggest fear has always been getting T-boned, mainly only the driver side, since I always thought I had crush space on the passenger side but from this example its pretty obvious thats not enough space.



My cage has the standard X plus a horizontal bar at the bottom, but as you mentioned due to the height of the miata the horizontal bar wouldn't have done anything. If I had a vertical bar on each side of the X, say about a foot from the center on either side, with taco gussets, how effective do you think that would be in a situation such as this? I think it would be fairly efficient because you would have two continuous bars(horizontal and one of the x bars) plus the two half bars of the x all having to bend in unison.

red = bars, blue = gussets
