Why were fuel efficiency ideas rejected?

It is not really clear to me why most fuel efficiency ideas were rejected in the past. It does not make sense. Surely there were no high gas prices five to ten years ago. I think at that time we could really afford to buy gas without suffering much. But there were a few hints and issues that could have told the auto companies that “hey we should probably increase the efficiency of our products”.

First there was smog. Smog is causing an increase in the number of respiratory illnesses around the major cities. People were being diagnosed every day. There were even those who died from the severity of damage to there lungs. That should have been reason enough. But if that was not enough there was also the issue of acid rain.

Acid rain is formed when the gas emissions containing sulfur dioxide, nitrogen oxide and other emission products combine with rain water to form acids. The acid rain causes the deterioration of metals and other materials in building and such alike. It also threatens food supply in that it was armful to both fish, plants and other animals.

There was also the mention of an increase in global warming which has the effects of causing more hurricanes/typhoons, tornadoes, drought, flooding, melting of the polar ice caps and the complete destruction or wipe out of small islands.

Scientist also told of the possibility of oil shortages in the future because the amount of oil in wells had already passed the peak. They said danger was ahead and the best thing was to change out the fuel systems before it was too late and start using the alternatives.

Was that not reason enough for these companies to changes their ways and advance their systems to be more efficient and probably turn to the many suggested alternatives? Thankfully our independent scientist had not been deterred by disappointment. Most of them kept on researching even though their ideas were rejected. That is why in the near future they can probably do as Thomas Edison and so many other scientists did by selling their inventions on their own directly to the consumers. And let sleeping dogs lie.
