Firstly, I love levels and thanks for it.

That said, in general for any given comp package, I’d want the lowest possible level I could take and get that package. That gives more upward runway.

The regulation is at least partially informed by physics though.

Braking distances, road damage (scales with the fourth power of axle weight), bridge limits, etc.

If the limit could safely and appropriately be 49 tons for diesel trucks right now, it probably would be.

Isn't "able to sell them at higher prices" a consequence of and an indicator of the demand by buyers?

Surely, if buyers didn't want these vehicles, makers couldn't sell them at high prices, right?

They already have another money printer that they’re perfectly happy to rely on, at least for the time being.
