The following is my understanding of this...it very well may be wrong....
I learned more editing images over the winter then I did by taking images over the summer last year. I am a big fan of the tail end of the car being a bit "soft". This requires knowledge of depth of field...and being able to judge how many feet you are from the subject. This image

was taken with a 50mm f/1.4 lens. the f/1.4 means the aperture, the size of the opening in the lens, is very large. And because it is a relatively short lens the "angle of view" is also very wide. Which means that the image is very wide....which I don't like. The front of the car is far to "soft" for me....this was because I was a bit to close and ran out of the depth of field..which is the area that is in focus. Confused yet? I was to close in an attempt to avoid taking an image with a lot of space around the car. While I could have simply stepped back, which I did frequently the problem then becomes noise (grain) will often be introduced when the image is cropped....least that is what I was told ‍♂️♂️. Solution for me was to buy an 85mm lens with the same f/1.4 aperture. The 50mm lens has an angle of view of 46.8*, the 85mm has an angle of view of 28.6*.

This simply translates into not having so much open space around the car..and still having the car fall into the depth of field...least that is my understanding of it ...ok....now that I have put you all to sleep I will be buy shortly to steal all of your toilet paper....
 
My wide is into photography, so I actually understood this. And I need toilet paper.

How about I pick you up in my van so we can stay 6 feet apart while we "commandeer" some supplies!!
 
Depth of Field Table

You can print off a table for the lens/sensor size you're going to shoot with and use that to know what will be in focus (remember, though, that you're shooting at an angle, so have to project that accordingly (or use trig if you want to get all mathematical and stuff ;-))
 
The longer the lens the shorter the depth of field. The wider the aperture the shorter. And the other problem with using a short lens and getting too close, is that the close end of the car starts to distort "larger" in relation to the far end of the car.

As digi cameras improve, so will the high ISO quality which will help, as you could then use higher iso/ smaller lens aperture to increase dof and help lens quality.

Only so much you can do "in the dark" lol
 
Is that why cell phones suck at taking pictures at a distance?
 
I actually know quite a bit about photography, but I did not understand the question. Depth of field is a function of the F stop and distance from the subject(s). For instance, If it is daylight and you have a person standing 10 feet away from you and a car behind them 40 feet from you, and you leave your lens on F1.4, you will have to use a fast shutter speed. With that 1.4 lens opening, you can either have the car be in focus and the person a bit fuzzy, or the person in focus and the car a bit fuzzy. The 1.4 F stop will give you a shallow depth of field. However, you could go to a slower shutter speed and a smaller F stop combination (say 1/60 second and F22) that will give you the same exposure, but a much deeper depth of field. You could probably get both the car and the person in focus. Most lenses have a depth of field gauge on them that can be quite useful. The same idea could be used to have the rear of the red Chevelle in focus and the front a bit fuzzy. However, other than kind of understanding what you mean by liking soft rear ends (I'm sure their is a great joke there), I'm not sure what the actual question is.
