I love LR, and use it a lot in my work. However, even the newest Creative Cloud version of LR is mostly limited to making global adjustments. It is not really designed for pixel level adjustments and repairs, which is what you are effectively asking for. Photoshop is the tool of choice when you need to do this sort of work.
You are running into one of the most fundamental and important photographic decisions you will have to make in this modern age: You can either spend a bit of time to take a good photograph (ie, stop the car) that won't need much post processing, or you can spend a lot more time trying to fix up a bad photo, and the result will never be as good, even if you are the world's best Photoshopper, LOL.
Of course, there are situations where one is perfectly happy to spend the time after-the-fact in PS, e.g., the photo situation simply can't be re-created / re-photographed / re-lived; your real interest is in learning the techniques and this photo is just an excuse to do so; the result doesn't have to be perfect; you're retired and have lots of time on your hands; etc.
Personally, I have zillions of photos just like yours that I've also taken out of car windows, especially when rushing around on a trip. I can only think of a couple of cases where I spent any time trying to fix such problems. Instead, I almost always leave them as they are, and mentally place them in my
"personal memory jog ONLY" category, to be seen only by my wife and myself, and enjoy the glitches (like your light pole) for what they are - true memories of that trip, not some doomed attempt to make art out of the proverbial "sow's ear", LOL.
Just my $0.02,

PS - Hopefully, I'm not belaboring the point, but just for fun, I dug up one of my own examples of the difference between a
"memory while driving photo" and what u can get if you pull over for a minute and can pay attention to photography, not driving. These two shots were taken a minute or two apart, the 2nd one, a hundred feet or so further down the road, after I pulled over, looking 90 degrees to the left.
I could have Photoshopped the 1st one till I was blue in the face and it would never come out as good as the 2nd (still no prize-winner) . Both were taken on the same little point and shoot camera. Of course, I did increase the contrast and saturation in the 2nd shot. OTOH, photographic improvements notwithstanding, the 2nd shot gives me absolutely no sense of where or when I took it, whereas, from the 1st, that whole day comes back to me, even if it is a complete failure from a photographic POV.
