Up in Canada it's similar across the board. Can we get someone to chime in from Mexico?

Ok you got me, I don't know the vehicle codes of every state, nor am I an expert on them in any state. But I can tell you that people drifting into other lanes on occasion is a thing that happens, usually without it being a big deal. Sometimes by mistake though I gave you a scenario where it is arguably reasonable. I don't dispute that it can also be dangerous, especially with big trucks.

While of course the lanes are there for a reason and should not be ignored, the relative positions of cars is the more important thing and our visual sense of where other vehicles is a thing we generally take in from the vehicle body and the expected consistent shape of them. And it is what we intuitively use when having to make sudden maneuver. Making your car have an unexpected shape and width below the body is asking for trouble.
