No disagreement with what you said but hasn't the whole pitch for Tesla Semi been for short hauls right now? Short hauls make a ton of sense on paper, limited highway miles where energy use can be highest, lighter loads and more stop and go. With a ev semi it seems that you might be able to take a large part fleet maintenance out as well as fueling logistics.

Explain why short hauls make sense. Your post doesn't show it.
Probably just throwing food under the bridge but here we go.
Short hauls:
1) Are at slower speeds which for most EVs means greater efficiency.
2) Have more stop and go driving which is more efficient in EVs compared to ICEs. I don't have the papers handy but IIRC there can be more pollutants generated in the acceleration phase of a vehicle, another reason EV makes sense for short hauls.
3) Park at the same facility at night which can have charging setup. Long hauls, unless specific corporate routes, do not have charging infrastructure.

1 goes for any vehicle.
2 yeah, nope no source. EVs weigh more and therefore pollute more when braking so should not be used in cities.
3 no advantage compared to combustion engines.
