I'd like to see slow trucks drive in the right lane rather than the left lane, and I'd like them to stay within the lane lines whenever possible rather than randomly drifting across them.

Stupid question, but to this day I can't get the idea of overtaking. Any given stretch of the road has a speed limit. That limit is well below the maximum capability of almost any car on the road. From the POV of traffic regulations, you'd expect drivers on either lane to drive at that limit. What is, then, the point of overtaking? The cars are swapping places back and forth, but otherwise are (supposed to be) moving at the same speed. Is it a way for some to work around speed limits (by always overtaking forward, never being overtaken), or just a pointless dance to keep drivers from being bored and falling asleep behind the wheel?

Drivers are supposed to keep right (outside/slower lanes) except to pass. That's the law in WA state and probably in most parts of the country. As far as I know it's also the law in other countries too; offhand on the Autobon.

In theory, the lanes further left should be at about the speed limit and the lanes to the right could be for slower long haul or dangerous loads driving, such as large and heavy trucks which might have a lower speed limit on some sections of road. In practice, please keep right except to pass and don't cause a traffic hazard trying to enforce slowness upon speeders with a rolling roadblock.

Yeah one wishes it would actually work like that.

Unfortunately there’s many drivers that drive below the (already low) speed limits.

Add to that curvy road and it becomes much worse (you can drive much closer to the limit by accelerating and braking dynamically).

I would conceed that keeping drivers awake is understated, though, the speed limits are too slow for modern cars. I comfortably do 15 mph over (freeway driving when road conditions support, I dont speed on surface streets), and id do 20-25 if it didnt move the penalty to jailtime.

I do this to save time, it cuts ~25% from my commute. My only recommendations are that slow traffic keep right (which is still me, traffic moves fast here), and be mindful of the flow of traffic. The most dangerous aspect of speeding is the speed limit, some people are inclined to follow the speed limit whatever it is, and become a serious hazzard when people are trying to cut through traffic at twice (or faster) that speed.

Where do you live that speed limits are only 45mph on freeways?

Speed limits are 55, sorry, sometimes I have a case of shiftwork brain. Northern virginia, if you watch those "idiots in cars videos" then youve seen these roads.

Overtaking doesn't happen as much on long haul stretches of highway, in accordance with what you'd assume. Mostly it's either passing a truck that's going under the limit, or because a truck is slower going up an incline. Once you're in a more occupied area though, a lot of overtaking is people going at the speed limit passing local traffic that's merging on/off the highway at lower speeds.
