There is no "global warming", and the air in general is not saturated with pollutants as some people would have you believe. Why don't you present some CONCLUSIVE evidence of credible scientific research that clearly illustrates global warming and cars being the #1 cause. >>
SsZERO,
It's easy for you to state that, because, in all honesty, it is impossible - as you, and many others know - to provide a causal link to a phenomenon that could be natural or artificial. It is unfair for any organization (scientific or otherwise) to claim absolutely CONCLUSIVE evidence that provides a causal link, with cars being the number one cause, of global warming; in addition, however, it is neither beneficial nor even moderately intelligent for you to refute a preponderance of evidence by demanding absolute proof.
What I'm getting at is this: an organization cannot, and will not, in good conscience, claim that cars will bring the apocalypse; however, in order to gain some glimmer in the eye of the public, they must make some claims that will allow for an environmental conscience to have
some hope in competing with the avaricious nature of the SUV and gas-guzzling car market. It is the nature for a theory (and global warming is exactly that) to have some holes; that is, in fact, the nature of a theory itself. Over time, it will evolve into something that becomes more and more concrete - yet at this time, the fact that it is not "concrete" yet does not make it invalid.
If all you want to do is sit there and spout rhetoric, that's fine. Don't, however, put down the fact - and yes, this is a fact - that humans are impacting our environment in negative ways, both in our direct effects upon the environment, and in the results those effects will have on us. We may not ever have proof that the impact cars have on our environment is catastrophic; yet we have enough understanding that by reducing emissions, we will be doing something that is - on the whole - a "good" thing. Forgive this drastic summation, but it is late, and I am tired.
If you don't want to give up your car, that's fine. If you would rather drive a 10mpg guzzler than a 50mpg fuel-cell protocol vehicle, that's fine. But please, for the sake of progress, don't discourage those who are trying to figure out what is at the root of many of these recent environmental problems, and don't be so dogmatic about the nature of your knowledge. There are many researchers out there who could put your "knowledge" to shame and debate you around the clock - and, I might add, whip your ass at it - in this realm; unfortunately, none of them are here.

Oh, and to stick to the topic: I agree - electric cars do suck. Hybrids, fuelcells, et. al, however...
