I personally think this car, and the others designed to
"drive into a tornado" are just a big publicity gimmick.
None of these vehicles or drivers are going to
survive an F-3+ tornado. No driver or support crew will
be able to accurately know the intensity of a tornado
since we all know the intensity of tornadoes can vary in a
brief amount of time.
Even the best designed NASCAR race cars can only
withstand a single "direct" impact of about 120 mph without
potential serious injury to the driver. In a tornado,
additional physics and debris come into play.
Lastly, if one of these cars are deliberately driven into a torando, and the
vehicle impacts into a home, person or another vehicle, I'll
bet the driver, crew and sponsors would be charged with negligent
homicide.
