Apples and oranges. The amount of energy required to move your bodyweight from point A to point B is something that can't be improved by technology.
I'm a big fan of new technology, but I'm also educated enough to discern between BS and reality. Golf carts/electric wheel chairs are good applications for rechargeable electric transport. They provide good utility transport over a short range. The cost to go with a hybrid e.g. Prius or Ford Escape increases the cost of the vehicle far beyond the gasoline savings available to the owner. It is "feel good" technology that accomplishes little.
The amount of energy to move you from point A to point B is not fixed.
It varies based on how fast you want to go, drag, effiency and the amount of excess weight you drag along with you do do the job.
The automobile is very effective but it is a hundred year old idea. There are other ways to get the same job done and some days people will be amazed that we got into a 6000 pound mechanical contraption with hundreds of moving parts to get around.
Keep this in mind, we burn about 200,000,000,000 gallons of fuel, kill about 50,000 people a year and spend hundreds of billions of dolars a year creating reinforced roadways to handle these heavy beasts.
I love my car and don't plan on giving it up for something less usefull, but on the other hand, I don't want to be a "buggy whip" salesman either.
