re: smug
Look around you and tell me what you see that was actually manufactured in your country. Mostly you're exporting your emissions (to China, among other places). Us too.
In the same way, a lot of people seem to be quite happy to let other countries drill elsewhere so they don't "pollute" their own nations.
I don't know which car you're talking about. We can get "smart cars" here too that get great mileage. They have the added advantage of not needing parking--you just pick it up and carry it in with you.
Again, it's a lot easier to keep national transportation emissions down when you can drive across the whole country in an afternoon. Makes rail systems--which cost by the mile--a lot simpler too.
