This seems to be a consistent theme in c&c requests. In that respect, you are not alone, however, ...
You can't take a photo that ignores all the values of good photography and then apologize for just not doing what it takes to have a good photograph.
Let's set up a little scenario I see as similar to your post.
Your wife comes home after a day at work where she's not been given a gold star for effort. The ac in the car is on the fritz and she caught every red light and then some on the way home. Traffic was near suicide inducing. She stopped at the store to pick up something for dinner and the check out guy couldn't figure out how to make the change from the $20 bill she handed him despite the fact the right amount was showing on the cash register.
She's rather hot and tired and not in the mood for BS.
As she walks in, the first thing she sees is the kitchen is a mess from the PB&J sandwich and chocolate milk you made for breakfast. Even more so from the frozen pizza you heated for lunch. Crap is everywhere and the dog has pooped and peed on the carpet. Then thrown up the pizza crust you gave him.
You forgot to walk him or even just open the door to the backyard so he could go out. The house is a disaster and hasn't been dusted or vacuumed as you promised. She finds you laying on the sofa in your shorts and watching Three Stooges films you've seen a hundred times before.
You greet her with, "Honey, you just missed the one where Curly gets his head stuck in a ... "
You notice the scowl.
"He gets his head stuck between the pipes and Larry can't find the big wrench so he grabs a hammer which Moe takes and ... uh, ... whassup?"
"You didn't take out the garbage."
"No, not yet, it isn't full."
"It stinks!"
"Can't, it's not full."
"You got Cheetos all over the white sofa."
"I haven't finished the bag yet."
"Why is the kitchen such a mess?"
"I haven't finished the bag yet."
"Where are the kids?"
"Which one?"
And so it goes.
If you have to admit you know you screwed the pooch when you took the shot and ignored the advice you have seen in how to guides, then, what was your purpose for taking about 100 shots? 100 bad shots taken in a location that is doing nothing but distracting from the photo.
You see some of what is wrong with the shot, so do we. You can't apologize it away just because.
Your reasoning for "blurring" the background - which you didn't accomplish - is because the background was "detailed"? It would have been much simpler to place the car further away from the bushes so the dof of the shot was more likely to create a real blur. It would have been better if you would have reversed your thinking and realized you wanted the main subject to stand apart from the background.
Lines are a part of the composition you create. You don't say, "Too bad the parking space markings detract from it. Quite reflex heavy on the windows, as I didn't have the right lens." The lens is not the problem here, you need a filter if you are going to take a shot such as this. Or don't take that shot, move the car. And the lines are more than "too bad".
There's not much to say about the shot IMO. You've pretty much shown us more than enough ways to not make a good shot and how to use a boring background with distracting elements.
Saying you kinda knew you did it wrong but didn't care enough to do it right and would we please ignore the fact you don't have a very good photo out of 100 shots doesn't leave much to go on.
