Yeah, I'd agree. Just my opinion, but I think it's fairly unrealistic for most folks to actually plan on reacting to an impending crash in a particular way. If you do react physically, it will likely be purely instinctual. And many collisions occur without any warning at all. Better to just develop good habits while you're driving and let the safety devices do their job in a crash IMHO.

By not driving impaired or distracted or tired, practicing prudent defensive driving practices, and always wearing a seat belt, you're about as well prepared for a crash as can be reasonably expected IMHO.
