Electric engines are capable of insane torque, but prolonged operation in such a mode is far from efficient, cool and preferable from a reliability standpoint.

Electric engines are capable of insane torque, but prolonged operation in such a mode is far from efficient, cool and preferable from a reliability standpoint. Two seconds at the green light - yes, plowing your field with a Tesla - no. So I can see it making sense for vehicles that have have two modes of operation, for example a tractor or all-terain vehicle that also need to work on public roads at relatively high speeds. A manual gear box is ideal in such a setting, because you seldom need to use it and it's very simple, cost effective and reliable. In any case, only useful for an extreme niche of applications.
