I'm guessing this is mostly because ICE vehicles waste more energy in town (due to braking loss, and engine inefficiency), than a problem with BEVs.
BEVs claw back the losses in town, meaning that only the simplest inefficiencies are left (v=ir^2^/2 with the wind and tyre resistance, and maybe a little bit of hot components reducing efficiency).
Those same highway inefficiencies are masked in ICE vehicles, as the efficiency is much lower during urban driving to begin with.
