As I understand it you can drive a car with two engines in the UK but you cannot drive a machine with two independent engines powering the machine at one time. Thus as I understand it a 2CV Safari would require one engine be behind a cut off switch rendering it inert on the public highway at all times. What you do off road is up to you, subject to liability law. This will lean on road law weakening a defence off road in an incident with a twin engined car. I believe Locomotives can be twin engined but then that is a very limited class of vehicle. It might be noted that older type road-sweepers often had two engines with one powering scurrifyers. I think you will find for ease of use that many were classed as Locomotives as it might be argued the scurrifyer is aiding the movement of the vehicle. This was why they were a mobile chicane even when not cleaning the road. Technology has moved on a bit and road-sweepers are a bit more sophisticated now.
Electric motors have far greater capacity to be linked together for control than two independently running IC engines. Thus I can see them being allowed to be used.
