35.5 is interesting...In the 70's I had a VW Rabbit that would get over 40 mpg and my Honda Civic HF would get close to 50 mpg and today we brag how the Hybrids get 50 mpg!!!...
I have a 2010 Mazda 6 that gets 34 on the HWY and I opted for the smaller engine.
As for the replacement of oil there isn't anything even close to gasoline if you compare its BTU output vs amount used. This has been the problem for a long time. So what you are looking for either hasn't been invented yet or the production of "it" uses more energy to make it than it actually produces.
As for electric vehicles there is one thing people don't think about. Once the demand goes up for electricity than so will the cost. If everyone drove vehicles that ran on water than the price of water would go up.
One last thing..one of the largest uses of oil is making rubber and plastics. How come the price of tires doesn't go up if their is a hurricane in the Gulf of Mexico!?
