It is not difficult to recognize them . Generally, accelerating is the maximum emotion generated by driving a vehicle. They zigzag on highways and do not think that anyone dares to walk at less than 60 kilometers per hour. With dark glasses and a slightly reclined chair, driving a car is an extreme sport for them. They enjoy seeing the face of terror in their passengers that drives their vehicle exceeding the established speed limits. They keep their own records and count, euphoric and whenever they can, their latest automotive feat. The speed limits are just landscape: they go at their own pace (usually double the others).
What they do not know, nor take into account, is that, despite their skills, they have an enemy in common with the rest of the mortals: physics. They are not aware that, while driving their vehicle, they are transforming large amounts of kinetic energy that ultimately, if not controlled, is delivered, deliberately, in the form of a traffic accident.
A mathematical formula is the one that, in fact, explains why in the big cities and highways of the world the speed of the vehicles that travel them is controlled: ½ mv ^ 2, or 1/2 of the mass by the speed squared. It means that, at higher speeds, greater kinetic energy will carry the vehicle. Since the mass of a vehicle is not very variable (it only changes by the number of passengers or cargo that it can carry) the authorities focus on regulating the speed of the vehicles, which is a controllable factor on the part of the drivers.
Other factors that affect when a person decides to drive a car at high speeds are their physical conditions. While a person driving at a normal speed can have a visual range of 100 degrees, when driving at 100 kilometers per hour this angle is only 45 degrees , which increases the risk of driving, because the person does not have a visual range adequate to give you sufficient control over what happens around you.
It also plays against the detention time, which is another mathematical formula where the reaction time of the driver with the braking time of the vehicle is added. Although the reaction time, which is the time it takes a driver to pass the foot of the accelerator to the brake, is calculated in a second , it varies according to their physical and psychological conditions (your dexterity, your state of mind, if you are tired or distracted, among other factors). The braking time of a vehicle can also vary depending on the mechanical conditions of the vehicle (the condition of the tires, the brakes, etc.) and the weather (if it rains and the asphalt is wet, for example).
For all this it is possible to deduce the importance of carrying out periodic thorough maintenance of the vehicle, so that its active safety devices (brakes, rims, suspension, steering, among others) and passive (airbag, seat belts, chassis, etc.). be at your point and avoid a traffic accident (in the case of the first) and reduce the possible injuries that can be generated in the driver or passengers in a possible traffic accident (in the case of seconds).
