the European Committee for Standardization voted to “develop a European Standard which reduces the impact severity of motorcyclist collisions with safety barriers."
This illustrates that most everything is outside our daily notice, but is very important to someone, and means life or death in this case. I gave it a bit of thought, and realized that the design of guard rails on highways is really important to the motorcyclists who have to avoid moron drivers who are usually causing bikers to crash.
