He did admit that he has no idea how the thing operates or whether it has any cost savings benefits. I took the conversation further by speculating at what point the vehicle becomes truly un-economic to own. We both came to the conclusion that there is a very real possibility that when the batteries need replacing the car will be at such an age that it's residual value will probably be exceeded by the cost of replacing the batteries and the whole car will just go for scrap. The real point is of course that we as consumers don't really know the cost of this tech, in real terms, either to our pockets or more importantly to the environment.
Prii are well over 200K on original batteries now - extending useful lifespan long after many ICEs have ceased to be an economic repair.
In short, we do know.
