GM had a car I believe was called the Insight back in the 1990’s that was way beyond it’s time as a gas electric hybrid. They only allowed the cars to be leased and when the leases were up, they refused to sell them, collected them among protests, hid them and had them all crushed…… They can make more efficient cars but do not chose to make better steps that are economically friendly….. money trumps green unless you are Ed Begley Jr so maybe they need to fail and restructure uner the guidance of a chaper 11 judge to smarten up enough to offer more efficient vehicles….. natural gas is the answer.

Also Luckyman if you took haulage, aerospace etc out of the equation your left with between 14-20% of transport using fuel… of which is made up diesel and petrol cars, which would definatly make your figures WAY OUT. With some rough mental maths i think you would only be saving about $25million a day in the U.S, which is almost nothing on the grand scheme of things… not worth the effort when theres alot of other things that could be done to save money. I mean americans could just eat 25% less and that would save on alot of fuel in transportation and cooking, and that just one example of saving money, which would be more effective and more viable than the electric car with no real drawbacks.

Cheers everyone
