Probably mostly correct. We are not necessarily stuck with lithium for long, there are a plethora of alternatives and more to come. http://charged.io/10-alternatives-lithium-ion-batteries/ If say graphene supercapacitors streaked ahead it could change the economics but consumption of oil would be displaced into fertiliser, plastics etc. The world population is growing nearly exponentially, oil is going to get used till it is gone I fear.
problem with electric cars is that when oil is under $50 its not worth it to spend an extra $5K when gas is $3 a gallon . The only thing that will make us change to electric is government regulations like england saying buy 2040 there will mandate no gas cars .
Well....for some, the buisness of importing and exporting oil across the world comes with a huge amount of political clout. You don't bite the hand that feeds you, and politicians know that best.
Even electric cars need to get their energy from some source. That will most likely be an oil or coal burning power plant. The net effect will then be that the exhaust gases will be at an other location. Not at the tail pipe of the car, but at the tail pipe of the power plant. Assuming that most electric cars will be used for small distance city trips, this means that the fumes are moved from inside the city, to outside the city as most power plants are located outside cities.
Things are changing however. The incredible creativity of material science is yielding huge dividends. While we won't likely have say thorium micro-reactor cars for various reasons though big advances are being made in power generation and reducing transmission losses. Thorium powered roads?
They will still use all the oil in other industries. edited: oops I intended to edit not make a new post.
your vehicle combustion engine is exponentially less clean and efficient than a power plant ; coal included.
