It was a better time unless someone can't drive to save their life and needs nanny features and ultimate performance just to safely drive the speed limit on public roads. The one exception is of course that we had to improve fuel economy because oil IS a renewable resource but only if we use it at an equal or lower rate than it is formed.

No. Solar? No. Nuclear? No. All these require raping the land and exhausting resources. Only solar generated biofuel is self sustaining in the long run.
