I hate hybrid cars, I hate electric cars because there wont be a vernerable supply of batterys to even open a "swapping" location for some time. IE- like changing the tank on a fork lift. it should be that easy to "refuel" an electric car when your traveling.
hybrid cars are a bunch of yuppie horse shit IMO. check out how locomotives work, you'll see that the diesel engine they use only turns an armature to generate electricity. why we havent adapted this to automobiles in the past 50 years I don't know.
Solution Hydro electric power. -
there were kits to take full frame cars that weighed around 3800-4100 lbs and get 60-70 mpg in the 70's. why we can't EASILY get 90mpg in a fully loaded 2500 lb car with a small electric/diesel is beyond me.
