Battery and electric vehicle lifetime costs (including electricity) are rapidly approaching the manufacturing and maintenance costs of internal combustion engine vehicles. That means that even if the fuel is free, it will be cheaper to operate an electric vehicle.

Low oil prices can delay that cost intersection, but won't prevent it from eventually happening because internal combustion vehicles are more complex and costly to maintain even without taking into account fuel costs. So as long as EV manufacturing costs continue to decline and electricity continues to get cheaper from low cost renewables, ICE vehicles will eventually become obsolete no matter the oil price.
