In my days of driving instructor, we usually ran a clients of teaching of the basics of threshold braking exercise (that is, after all, in the days before anti-lock brakes). You could configure braking chute, marked by cones spaced seven feet of separation; It is narrower than one lane of traffic standard, but still far more extensive than most of the cars. What to learn? 60 Miles per hour, even experienced drivers had a hard time judging the width of the chute braking, resulting in cones release deeply in the infield of rattlesnake-infested. Good times, good times.
It makes the video below more impressive, if it is real. It can not be judged the speed of the driver well, really there is no reference points, but trust me, he is hauling ass. If you really have the talent for the needle through a series of 1 concrete walls up crossed m at speed of deformation of thread, my hat is actually out to him. It is real or is it CGI? See the video below and tell me what you think.
