" Science may have found a cure for most evils; but it has found no remedy for the worst of them all- the apathy of human beings".(Helen Keller).

The combination of a VICIOUS CIRCLE and an INFORMATION GAP are the main features of the universal background, fed and supported by the PRESSURE OF LOBBIES from the truck owners and manufacturers, and by IGNORANCE AND CARELESSNESS.
