I saw a news story about 10 years ago about a couple who were having sex in their home with the blinds open. A neighborhood kid filmed it and the kid’s parents ended up finding out. The couple was arrested and charged with indecent exposure.
I don’t see sex in a car as any different, unless you can do it without exposing your genitals.

Finding a spot that cops don’t patrol and neighbors can’t see: Priceless.
It would probably depend on the when and the where. My girlfriend and me got caught when we were twenty somethings. The cop was pretty cool about it, he had my girlfriend get out of the car and walk back to the patrol car with him. His purpose was to seperate us and make sure that it was consensual, after making sure that was the case he told us there were probably better places to “stop and liten to the radio,” than this spot and left.
Meh, what’s the point if neighbours can’t see ?
It’s not the neighbors, it’s her parents that counts. 
Reminds me of the story where a woman called the cops and said her neighbors were exposing themselves in the next apartment building and she could see them from hers.
The cop looked out the window and said, “I don’t see anything.”
“Stand on this chair, you can see them much better.”
I was busted as a teenager in So. Cal. and it was more funny than anything. My girlfriend and I were very busy fogging up with windows of my pickup truck when we were very rudely interrupted. The windows were completely fogged over I had to roll down the window to see the officer.
The deputy said some folks had reported a suspicious car and we’d better ‘move along now’. We drove somewhere else and started all over again.
Aaahhh youth.

Oops, John Prine credit.
It’s okay in NY as long as long as no one is likely see you.
It’s very illegal if it’s someone’s car you’ve just “borrowed” in the heat of the moment. 
I recall back in West Texas there was supposedly some sort of law stipulating that teen couples had to be wearing their shoes in the car or else risk getting busted for something or other. The whole thing could have been just an Urban Legend, but I knew a guy who claimed he ran afoul of a hard-ass cop who wrote him up for not wearing a shoe. He was not wearing a shoe because he was wearing a full-leg cast, with just his toes sticking out. Allegedly the cop said that was enough. I am now reminded of this and wonder if anyone has ever heard of such a law for real. And I don’t mean a law that says you can’t drive barefoot or anything like that. I mean a law that says all occupants must be wearing shoes or it could be considered indecent.
Posting from NY, and all I want is a simple YES or NO answer to these questions below.
Is it illegal to have sex in a car while the car is in a public place? Like a parking lot, park, behind buildings etc.
Is it illegal to have sex at a town park in/on the playground?
Is it illegal to have sex on a hiking trail near that park?^
Is it illegal to have sex behind/inside a baseball dugout?
Is it illegal to have sex in a church or on the back steps of a school?
And finally,
Is it illegal to do all of that IF you don’t get caught ever?
(Keep in mind, these are only a few places I’ve done so)
Yes.
.
Yes, it’s still illegal, even if you don’t get caught. Go turn yourself in like a good citizen.
Back in my teenage years the backseat of my folk’s Ford LTD got quite a workout when I borrowed it for dates. As an adult, I can testify as to the quietest areas of the Pike Place Market parking garage for automotive erotica.
Would I , could I, with a fox?
Would I, could I, in my socks?
When I was a teen in school in Los Angeles, circa mid-1960s, we were taught that any boy caught with an underage girl in a car, absent any item of clothing that would normally be worn, would be arrested for statutory rape.
The law, as we were taught, didn’t specifically mention shoes. Only the rule about not wearing the usual clothes. The police interpreted that to mean that if you so much as took your shoes off, it was statutory rape.
It was a loooooong time ago, and we were parked, along with 3 other cars, at the top of “Chrysler Hill” outside of St. Louis. Chrysler Hill was a favorite “parking” spot, at the end of a long dirt road, with a great view of the valley below, totally in the middle of nowhere. We’d done it many times before, but this time a cop drove up and began shining his light into each car. One by one, intimidated, they started up and took off, but I decided to challenge the system (what’s wrong with sitting in a car on a lonely road?)
So when the cop shone his light on me, I gave him one finger, then one for each hand. Take that, you pervert!
He turned off his light and drove away. Nothing to see here, copper. Good times.
Today, I would have been tazed, shot, or worse.
I was 16 or 17 and found a nice secluded parking lot behind a church. It’s past midnight and who’s going to be visiting a church at that hour, right? Well, 10 minutes into the deed, there’s a tap on the back seat window and my gf shrieks. It was the deacon(?) of the church. I pull up my pants and slightly open the door and say, “Yes?” He says, “This is a church. Do you mind?” I remember being pissed off that I couldn’t finish, more than being embarrassed or sorry.
16 or 17? Maybe there’s an age limit.
Would I, could I in a car?
It doesn’t matter where you are.
Yes, in a park.
Yes, on a train,
Yes in a car,
and a mile up in a plane.
Behind the buildings,
And in the dugout,
And inside of a church,
Hope you don’t get found out.
Those are the places the policeman expects,
For one to be arrested if one has sex.
Sorry. I couldn’t help myself.
