Answer 1

As the gas prices increase, the demand for electric and fuel efficient cars has greatly increased. People want to avoid spending more money than needed. With new advancements being made technologically, there is not much of a demand for cars that require excessive gasoline.
These new advancements have created a new era of automobiles which in turn creates job openings and economic growth in the auto industry.
Personally, I would rather purchase an electric car, or a car that is more fuel efficient to save more money in the long run.
