I like a lot of what you say, especially about cars and urban development (

Police... always always always make things worse
They don't always make things worse, as I discovered when a random guy pounded on my door in the middle of the night and threatened to kill me: http://jseliger.wordpress.com/2010/06/21/guy-pounds-on-my-do... . Cops are also caught in a nasty place because of drug laws, which leads me to my next point.
Nobody believes that our vote matters, that the politicians sitting in office will kowtow to anybody...
This is a self-fulfilling prophecy: if you don't vote because you don't believe your vote matters, and others do, then their vote matters and politicians will pander to them, not you. Old people vote en mass; that's a major reason we've having fiscal problems related to Medicare and why those are going to worsen as time goes on. Don't like it? Vote! Convince others to vote. Every election is a potential revolution, which is why we have them.
I voted today, albeit for a mayoral candidate who, according to the polls, is supposed to lose. I've never voted for the two major political parties in presidential elections.
WRT voting more generally, see Bryan Caplan's The Myth of the Rational Voter.
