Please, Let's Somebody Ask...

GM and Ford and Chrysler execs: "If we give you twenty-five billion dollars - how many more people will buy cars?". OR: "If we don't give you the money - how many people won't be able to buy a car?. Listen carefully to their response. My own guess: Very Damn Few. There are, of course, advocates of a bailout. As we see here: "The Future Is in Sight" says Jeffrey Sachs.
I'm sorry Professor Sachs; The Automakers have been promising "the pathbreaking (fill in the blank) set to arrive in (fill in the blank)" for forty years, and have yet to deliver. It's the same kind of empty "Trust Me" plea made by Big Oil when they promise that there will never be an oil spill - and besides, If There Is One, we promise to clean it up. There are oil spills - lots of 'em - and they're never cleaned up.
Same-wise, there will never be {Major Prediction Here} a powered vehicle that has no detrimental environmental impacts! This in spite of the strange and deluded belief held by so many that Electric Vehicles are non-polluting and cheap to run on that abundant-and-inexpensive electricity one can find in one's garage. Cheap if you plug it into your neighbor's garage, perhaps. Unless he reciprocates, of course. Figure about two terawatts/day of added demand for electricity, and shop around for a source, I says, before you tout the future of the Electric Vehicle
