Must be nice having such easy answers to real problems that you can either gloss over or pretend don't exist, Jesus.
(Pro-tip: cars aren't lighter and not made of steel because it would *kill* people in accidents, therefore making cars super fuel efficient is impossible on *physics*--it's not a lack of will, but a lack of a death wish that prevents this from happening.)
(The rest of the comments are just as blinkered and hare-brained, but I'm not going to waste my--or your--time picking them apart short to say: this person doesn't understand phsyics, economics, and a whole host of other subjects he's opining on as an expert.)
