Ok, I guess you are living in Vienna or at least in the area and are about 15-25. I may be wrong of course and it doesn't really matter.
In areas with a mostly working public transit system that doesn't look like the one in Japanese cities
during rush hour, having and driving a car is a sign of decadence and egoism indeed and having all those cars blocking the whole city, polluting the air and killing bicyclist like me who always follow the rules is bad and unnecessary. People don't want to see this because a car is a symbol of independence and maturity and they wouldn't want to give it up just for being a better person and treating their environment in a better way. People are selfish and vain, that's one of the facts of life you have to accept.
Regarding the hippies:
I got to know several kinds of hippies thanks to my job and there are so many variations, that you can't define any group as "the hippies". Some people use this term as a concept of the enemy, others as the concept of a perfect community.
There are for example the old American hippies which just wanted to show, that socialism CAN work on a small scale and with rather liberal than authoritarian attitudes (= the opposite of Russia). Those have usually formed self sustaining microvillages in the middle of nowhere and are usually happy until the next police raid that's officially done because or (mostly nonexistent!) marijuana and inofficially to intimidate people that are living an alternative way and are annoying the neighboring narrow minded cities by it. A good example for this is the one near Arlington:

The origin of "free love" wasn't promiscuity, initially it was just about the right of students to live with their partners. In the fifties and sixties you got thrown off campus if you lived with your partner pre-marriage. Most of those were monogamic and just didn't like the concept of marriage or the pressure society has put on it.
Then at a music festival where I was working I've got to know an extremely well aged lady that everybody would consider to be a true hippie at first glance (dot on the forehead, clothing, way of talking, hairdo, etc...). She was living in the mountains with her husband and her 8 (!) children a really happy and secluded life with few regular expenses, spoke several languages fluently and traveled around for her work now and then (a diner wagon with high quality food). She was 68, looked like 35-40 and was a wise although a little weird woman.
Now to your attitude "tear down the walls of civilisation". Actually, this is a way of thinking you most likely adopted from the ones you don't like and just twisted it a bit. Maybe some people are happy with their egotistic lifestyle with their god Mammon, all their shallowness and polluting, etc... who knows? If you're not, than live another way as soon as you think you are prepared for it and have enough knowledge and the money to move away from the masses. Start your family there, to me it sounds like you have a similar problem like me, for several (mostly financial) reasons, I'm stuck in my hometown which I absolutely despise because it's too crowded, unfriendly, expensive and sociopathic. I just hope I can stay friendly until I'm out of here and so should you.
The reason why I play games has changed over time and so has the kind of games I play.
When I was a teenager, I loved Quake 3 Arena and Counterstrike. Whenever I got to use a PC, I vented my anger and got myself distracted from at the time unsolvable problems you can't even imagine. Today I play games like I read books. It's a mix of enjoying the art, trying to peek into the minds of the artists, getting rest after work, occupying my hands without having to move my tired body and also giving myself the sense of having achieved something even in my free time. Still way better than watching TV if you ask me.
In conclusion: Live like you would like to see others, be a good example and try to maintain a smile while doing it, this way you might even give someone a nudge in the right direction. If you're environment doesn't fit to you, try to get elsewhere.
As you can see in this and other threads, your frustration is just alienating others instead of giving anyone an impulse to think about their habits, in order to improve humanity you need more than frustration and certainly not hatred, you need better ideas than others are having, long term dedication and a smile.
Everything else is just immature ranting, which is always part of the general problem with humans.
