There was once a demonstration by Tesla on electricity and the body. If he grabbed power lines with high voltage at 60 cycles per second it would assuredly kill him.
He theorized that if the same power were raised to 300 cycles per second that he could safely handle it. He went on to prove this very thing by grabbing high voltage live power at 300 Hz and walking away intact.
To me this demontrates that the possibility exists you could safely walk out in front of a speeding car if you could change the frequency of the car or yourself. If you cannot, then you most assuredly will suffer some damage or death.
It is great having pie in the sky Beliefs but having the technics to make them reality can be a big stumbling block. The answers are always there to make Beliefs become reality.
