CO2 from cars - are we gonna die? Really?

...or why the heck is almost everybody so concerned about cars having "some" BHP? Currently, there is some kind of rage going on about SUVs, big limousines, politicians driving big cars, and even our regular vehicle that gets us to work every morning produce so much CO2 that the climate will change and Belgium will drown. Furthermore, terrible thunderstorms will reach areas that have never experienced anything like this before, deserts will become forests and the other way around. To make one thing absolutely certain right from the start: I think it is absolutely correct that mankind should not pollute the atmosphere in general. And I do see the point that the climate will change because too much CO2 is emitted (although there are voices saying that climate changes comes before a rising degree of CO2 concentration in the atmosphere. As I am no scientist in this field, I'll just take the warning and believe it's crucial to do something against vast CO2 emission.
As I said, this is perfectly clear and obvious to me. But why do people get furious about CARS?!?! They make up for about 8.5% of the total CO2 emission in Germany each year. Another 8.5% are produced by buses, trucks and the like. This makes 17%. As those figures come from the ADAC (German Drivers Club), they might be biased, although 17% of CO2 emissions caused by vehicles of any kind is the highest nummber I have heard so far in that discussion. The "FOCUS", a quiet popular magazine that claims to be "objective" of some kind delivers data showing that Germany is producing 865 billion tons of CO2, while the US are emitting 5987 billion tons. Unfortunately, I don't see any time frame for that. I just assume its on a yearly basis. You can find the data in the 11th Issue of 2007 (2007.03.12). Seeing those numbers, I just cannot believe that politicians want to implement general speed limits on German Autobahns by referring to the CO2 emissions. Moreover, I don't see why the car is displayed as being "evil" for producing CO2. Every cow does. Agriculture makes up for 20% of the emissions every year. Now do you want to put a catalytic converter up every cow's bottom? Guess environmentalists would hire a professional assassin if you plug that on TV... (I know, bad example. But you get my point.)
The industry is - by the way - producing about 60% of CO2 emissions. Why aren't politicians eager to increase production process efficiency in terms of those emissions? No lobby there, ey? Interestingly, the lobby of the car manufacturers did not obviously rebel against measures and arguments. Maybe because their leader changed in the middle of those discussions...weird...hm?!

Nevertheless, there is a message I want to get across here - this is quite personal and obviously not to be generalized for Mrs. Merkel: If you really want to reduce CO2 emissions worldwide, focus on targets that are most promising. I know this is a utilitarian approach not much fancied in Europe, but hey, for the sake of nature, give it a try. Even if Germany reduces it's emissions by 10%, what would that make up for on a global basis (and the atmosphere knows no borders, countries, or whatever). Look at the US or China, for example.
Remind yourself of the figures I presented above. Remember the heavy duty trucks they use for everyday shopping. We can deliver our share here (more efficient engines, hybrids, less powerful vehicles, Diesel engines, ...), but let them take theirs, too. They have a much larger stake in it than we do. And stop asking everyone to "think globally". Start with yourself. Eat that, politician/lobbyist/environmentalist/in-box thinker.
