To Rodney Yo: I hope you would add information to your course on how to maximize a driver's safety like learning how to corner on the open curvy road by learning to set up a curve and apex the turn to minimize the effects of centrifugal force. Works well on freeway driving as well. When there is lots of traffic as at 4-way intersections.. teach drivers to look first where the first car might hit them (through traffic on the left before a car from the right would turn into you. Hitting standing water at 55 MPH may hydroplane a bald tire shod auto.. Would that happen at 50 MPH??? How do you react to a head oncoming car in your lane?? If you have obstructive sleep apnea and don't have corrective CPAP.. you can have your driver's license garnished...
