I think the answer is obvious to all of us. its the same thing with cigarettes. although they are bad, they keep getting used by the people and their great nemesis is the electric cigarettes.Those will replace the old usual cigarettes. and the same goes for the electric cars. Although electric cars are more expensive than the original cars. their price will drop eventually.Thats a fact.
So it will be quite bad for the oil industry since those cars will disappear by the passing of time as well .
Cigarettes are a bad analogy. People are trying to cut down on cigarette consumption due to the harmful effects on individual health. It would be a stretch to say the same about gasoline cars.
Plus, electric cigarettes haven't dented sales of conventional cigarettes at all.
Vape (electric cigarettes) might be better in terms of health care, taste, etc but Vape costs more than a regular cigarette. People prefer buying cigarette even if in the long run of regular buying, it'd cost more than a Vape does. They want to buy the cheap ones.
Just like for the cars, even if electric cars have been there, people aren't buying them. Simply because they're used to using an oiled car. Also, the electric cars featured in the TV (in my area, atleast) looks really different than the usual car. If they make an electric car that is a replica of an oiled car, then there might be some people who would be interested.
