Doug--
A lot of decisions on head-neck protection can be data driven. Some types
of data are easier to get than others. One type we don't have much of is
"g" levels experienced by car AND driver during LSR crash events. Our
crashes are somewhat different from what the circle track racers experience.
A good number of LSR cars record engine performance with data logging
equipment. I suspect that information has had very limited, if any, use in
SCTA investigations.
I wonder if the Shockwatch folks: http://www.shockwatch.com/ have a low
cost product that would be of any use here. They have a product called
"Micro Shocklog" that looks like a possibility.
Nascar has been using a "black box" type product from Independent Witness:
www.iwiwitness.com/ for several years to capture "g" levels in crashes. I
have no idea what this stuff costs; and the cost is likely in the chump
change range for a Nascar team.
Is there a place for that kind of stuff in in LSR? For maybe the faster
cars? I'm not sure we're ready to accept a mandate to install another
expensive piece of safety related gear in our cars what with next year's
likely requirement to spend in the $700-$1000 range for head neck
restraints.
Nevertheless the data accumulated would be valuable for us. Maybe we'd be
lucky and take way too long to get that data.
