There are cases where hybrids remove complexity because they can be designed to operate either without transmissions, or with substantially more simple transmissions. Hybrids are cheaper than EVs since a good chunk of expensive batteries can be off-set by an ICE. Hybrids are probably the end-game for any forms of transportation that require operation for a long period of time. A dump truck, for example, could have its 12L, 400hp diesel engine replaced with a 1L, 60hp engine that charges the batteries that drive the electric motors. Since the auxiliary engine only needs to be able to provide just enough juice for cruising, it can be made much smaller.
