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.

Ahhh you misunderstood my original statement. Sorry, thanks for taking care of the bridge though.
