I wonder is it is more of less efficient for land use as they don’t need fuelling and the associated land that uses, but do need a pair of lamp posts every 10m.
In many cities they just bolt these support wires into adjacent buildings when there isnt a convienent lamp post.
Electrifying core parts of the route (eg: the most heavily travelled bottlenecks these trucks travel) could fix this issue, enabling charging and heating the battery and cab while still en route or plowing snow.
