blue prints

Why are car dealers allowed to buy the blue prints of a vehicle that will revolutionize the world and keep it from us? This act is almost like knowing cigarettes are bad but not telling the people. Environmental cars should be out but car dealers have bought the patens, so that Americans have to keep on buying gas guzzling cars to fatten their pockets. When an idea is made that will save the ecosystem it should be open to the public for use. Not allowing the people to receive better treatment, service, and environmentally friendly products is a form of stealing, much like what car dealers are still doing to this day.
