Impacts due to large adoption of electric cars. A few electric cars is a non-issue. Large adoption will require a lot of system upgrades. A lot. Depending on the charge interval, they pull several households of power during recharge.

Of course, it's not just the line either; the presence of distribution neutrals and other grounded conductors in the vicinity of the line all help make the actual value rather fuzzy.
Maybe we should all have two values of Z0, wet and dry. Set zone 1 based on the wet impedance but make sure that zone 2 still overreaches for the dry value.

My suggestion was related to the fun of a young and bright mind fully understanding the physics of magnetics fields with earth and ground wire return, well enough to finding a set of equations that show the electric and magnetic fields around a transmission line. If all you need is the mundaneness of saying there are too many variables for even the most accurate model to know what is going on, and Carson's equations (or whatever Aspen and Cape are doing) are just fine cuz you can plug in p.earth till you get Zo results that more or less match what you see in the real world, OK, then I am glad you (and 99.9% of the power engineering world) are satisfied.
However, that does not solve my curiosity, and I wish I was a young guy with a big puzzle in front of him and a chance to show how strong and bright I was by figuring out a cool massive puzzle that I used to dream I was bright enough to figure out. If you really want to know current distribution and magnetic and electric field distribution, you are not going to get it from Carson's equations. I assume you next will roll your eyes and say, "Oh come on John" and say only finite element analysis will do that. Maybe true, but I want more than that answer.

I'd love to have single, calculable, value of Z0 for each of my lines. That would be a wonderful improvement over the present situation. No doubt what so ever. But should it be the March 15th impedance or should it be the August 31st impedance? Or, maybe the impedance on a balmy May afternoon?
Would it be the current distribution in the earth alone? Or, should it account for all of the current that returns above the earth in distribution neutrals? What about other linear conductive paths such as communication messenger wires. Railroad tracks can confuse the equation.
It would be a great academic exercise, thus perhaps a good PhD project, but I don't see it providing useful information as to how I should be setting my relays.
No anger or bad attitude. We had similar discussions over a decade ago and have just picked different windmills to tilt at.
