When vehicles stop because of a collision, this energy is transformed in gigantic forces that cause significant damage to both the cars and occupants. The energy level of the car and the occupants bodies, increases with the square of the speed, and it can smash and behead in a fraction of a second . Vehicles carry people and they, not computers, are in command of those vehicles. To drive a vehicle means to negotiate space at a reduced time, and it becomes critical as the velocity increases. The higher the speed, the less time is available to recognize a hazard, decide what to do, and to take the appropriate action to prevent a disaster.
People fail because they are human.
Usually they don t believe in it. They are not computers and make mistakes while driving. Incorrect judgment of distances and differences of speed are common causes of collisions. Correct engineering solutions are intrinsically linked to all human objectives, from the simplest project on earth to the conquest of space. Engineering is the basis for human progress since it is the intelligent application of physical laws and principles.
