Especially fatal accidents (which happen ONLY at high speed) which jam the traffic for an hour or more while the police investigators do their work.
True in many cases, but don’t forget about the law of conservation of energy, (energy cannot be created or destroyed, only changed in form). When two objects collide, the energy must be absorbed.
So if a logging truck hits a small car at low speeds, who absorbs the kinetic energy? The smaller of the two objects. At 30 KPH, a large or loaded vehicle can cause significant life-threatening injuries to people in a smaller vehicle.
And imagine what it could do to a pedestrian.
And for all you speeders, think about this: When you crash, there are three separate impacts, each involving the transfer of kinetic energy.
First, your vehicle comes to an abrupt stop against a foreign object. In this first collision, kinetic energy is absorbed by the deformation of your vehicle.
The second collision happens when your body collides with interior objects, (like the steering wheel, windshield and dashboard) in your car. When your car comes to that abrupt stop, your body is still travelling at the same speed as the car. The kinetic energy has to be absorbed, so your body takes the impact.
The third impact is when your vital organs, like your heart, lungs and brain, are hurled violently against your body’s structures like the chest wall and the skull. The brain can actually be thrown back and forth inside the skull as your body decelerates.
So, just why is it that people speed?
