Ever stopped at a traffic light?
You're a socialist. Traffic lights serve a common purpose without reference to a users' status or wealth.
Ever pulled over for an ambulance?
You're a socialist. You've acknowledged that whenever another human is in mortal danger, regardless of who they might be, what colour their skin, what religion they pursue, how much money they may or may not owe you, you will do your absolute level best not to interfere with or hamper any support that may come their way.
Ever called the Fire Service?
You're a socialist. You didn't pay for the incident. That was absorbed by the rest of us who pay taxes to maintain the Fire Service so that you don't get landed with an enormous bill as well as a tragedy.
Ever been a member of an automobile rescue association?
You're a socialist. Every time you see one of your association's vans providing roadside assistance you know that you're paying towards that motorist's spares and repairs. You might even be paying for his free ride home!
Ever used or stopped your vehicle for a pedestrian cross-walk?
You're a socialist. You don't know anything about the other party except that you've both agreed to and abide by a set of rules which apply regardless of either party's income bracket, political beliefs, or inheritance.
Ever bought an insurance policy?
You're a socialist. You pay towards a common central fund which agrees to pay out to you or any other contributors to that fund in the event of disaster or mishap coming your way. All contributors bear the costs of individual contributor's bad luck.
Ever called a cop?
You're a socialist. Rather than rely on your own courage, personal strength and/or weapons proficiency, sleuthing capabilities, or capacity for staying up all night to keep an eye on things, you pay into a central fund which covers the cost of these services, even if you never use them!
Ever relied on your nation's armed forces?
You're a socialist. Instead of fighting your own wars you buy into a scheme which allows others to process wars on your behalf (this may or may not be a good thing).
Ever played in a park?
You're a socialist. You're utilising geographical space which has been declared "common" without having specifically paid for access. You're cavorting on ground that has been deprived of speculative potential.
Ever used a paved road?
You ought to be ashamed of yourself.
The bulk of your examples means I'm a law abiding citizen, which has much more to do with authoritarian rule than socialism. Following the law of the land may be akin to communistic socialism, if that's where you're headed with this.
If you're making a point about Democratic Socialism, those things aren't descript of that, either, except maybe the fire department, and even then, if I'm not allowed to have a say in how they operate, that's a stretch.
And NO! Unless you were here and paying taxes when Pearl Harbor was bombed, the services of the American Armed Forces aren't anything that's benefited me or very few other Americans since the Japanese attack. (9/11 doesn't count because that was a total clusterfuck in the sky by our armed forces, a complete hot mess, if you will. And everything since that day has been for oil/resources, not citizen safety.)
And let's not forget ... parks are funded for the people by the people. That may be a socialist thing, if we all have a say in how, when, where, why the grass grass gets mowed. Otherwise we're just paying for someone else to run the show and make the decisions for us.
I happen to have socialistic tendencies. When I had employees, they had a say in running the business. That's not to say they made the decisions, but they were included in the process. I was still under the thumb of my government, however, thereby making it a moot point how I chose to run my own business. (And if the government would've taken my business assets and distributed them, I would be a socialist. But that's not how it happened.)
(Symantecs. For every example, there's an opposite example. For example.)
I don't care about labels. It's a viscous cycle. We're all just victims of circumstance at this point.
