Whilst we talk about the future impact on ICE due to fuel cost and availability, we will also find that the maintenance and spares infrastructure will also start to dimension/disappear as the traditional heavier maintenance requires of ICE with lower future volumes will see servicing requirements demand etc fall and with it the support structure. May not be petrol that kills it off but the lack of spares and skilled people to fit them.........
Agreed.
A bit like Steam Engines...
