I'm referring to a huge net loss from when you start up the mountain, not from the top o' the hill. You'll use up more energy going up than you can recoup from regenning down. Can we agree on that?
I was going to until No. 14 popped up. If you work for an anvil company at the top of a mountain and your job is to deliver to dealers in the valley then no, you don't use more energy going up the hill than you get back going down. But, of course, that's hardly a normal situation. Taking your family up the mountain to a park and bringing them home with regen you should consume only a little more than driving them to the beach and back (assuming that you live at sea level) and that "little more"comes from the fact that regen isn't 100% efficient (can't re capture all the potential energy.

Because it is empty going up, so the work going up is less than the weight and work done by gravity going down.
Right. But it proves the concept and really says that regen is pretty powerful stuff. Even if it only works in certain situations.

There's a hill on the other side of my village that going down I've gotten 5% SoC back. On a warm day, it barely takes more to go up it! The end result is going up and coming back down, I only have to pay for the straight-line mileage in range. As long as I get good regen (steady speed above min or heavy load), hills basically equal out.

The work that charges this trucks batteries came from whatever geologic force it was that pushed up the mountain,
Exactly, it only gives us free power, much like solar energy, if we ignore all the parts that cost, just because we didn't 'pay' for them.
(meaning, we didn't pay for the crust rising nor do we pay for the sun's fusion)

Why can't this be a thing?

The battery puts the vehicle in motion. While in motion, why can't the wheel generate electricity and recharge the battery?

I've got a radio at home that can charge by the sun as well as charge by turning the hand crank.
A wheel can be used to generate electricity while driving, however, the resistance that it causes on drag to generate electricity will have a negative effect and actually take more power to operate the vehicle. This only works during the regenerative braking or coasting when kinetic energy can be send back to the battery rather than being wasted.

Yep...I get it. I was just trying to think outside the box for ways to recharge the battery. Hopefully the concept of solar panels in the bed comes to fruition. :)

For now things will and do advance.

Things do advance, however, one can't get around the law of physics. Perpetual motion energy just isn't possible.
