Michael has raised a valid point that was discussed without resolution many
years ago and I think that Derf has also raised the better transverse
rigidity that a roll bar provides.
Why not provide a mesh from the top of the seat back up to the padded roll
bar? This may well assist in preventing the traditional whiplash neck
injury and remind you under normal driving that you are going to head-but
the bar as you lean back or stretch in the seat.
I don't know of any-one who has done it but I will be looking into it
further as my own motor progresses. There could be a 1001 reasons for it to
be impractical and it could have been done already but I can't recall seeing
one.

Well, if you get in a crash there is a very small chance that it would be
better to be thrown from the vehicle so not wearing a seat belt might have
some merit, right? People here in Louisiana used to say they wouldn't wear
a seat belt because they wanted to be able to exit the vehicle quickly in
case they ran off in a swamp or bayou. Point is there are always excuses
and justifications if you look for them.
Having had Spridgets with roll bars and Miatas with roll bars I'll say that
many are very good and enhance safety. There exists a double hump "style
bar" for the Miatas that is dubbed the "rat trap". I would avoid those.
Others, though, that have decent strength and good mounting points are very
good. Hitting your head is always a risk on a street car that allows soft
top function, unless you're a jockey. With a good padding, though, I think
the risk of hitting your head is negligent compared to the benefits of added
strength and stability, not just roll over protection.
With the Hard Dog double diagonal bar in the Miata, I was confident that a
yahoo in a jacked up pickup couldn't easily plow me under. Also, I'm sure
side-to-side rigidity was greatly improved.
