The problem is simply speed - at higher speeds it is easier to lose control especially on highways when the grass is about 4 -15 feet from you. Once you are off the road on wet grass with trees about 10 feet away you are absolutely at the mercy of physics and basically done. Braking and turning at high speed on grass will mean nothing. F1, Nascar, professional racers would be just as done on that grass. The difference is an experienced driver would know not to get into that situation. Unfortunately, for these kids they will never get the chance to be experienced drivers.
