Kinetic energy is only dangerous when an impact occurs. Impact's are not always avoided by stopping, many can be avoided by maneuvering or accelerating out of the danger zone.
For example, why is it that Colorado is one of the last states to require motorcyclists to wear helmets? Because as a motorcyclist they are more maneuverable and capable of acceleration beyond that of most cars, therefor it is safer and better to NOT limit the viability of a motorcyclist so that he/she can avoid the incident instead of try to survive it. No helmet = more situational awareness. If drivers in automobiles maintained half the situational awareness of motorcyclists we would have safer roads and eventually higher speed limits.
It is always the minority that are target when it comes to driving.
