Which of the following is NOT a governmental incentive for electric vehicle adoption?

Import tariffs on gasoline cars do not serve as a direct incentive for the adoption of electric vehicles. Instead, these tariffs are typically implemented to control trade and protect domestic industries, making gasoline cars more expensive to import. While they may inadvertently encourage consumers to look for alternatives, such as electric vehicles, as a consequence of higher prices for gasoline cars, their primary purpose is not to promote EV adoption.

In contrast, tax credits are designed specifically to reduce the cost burden on consumers purchasing electric vehicles, making them more financially attractive. Grants for EV manufacturing support the growth of the electric vehicle industry by providing funding to manufacturers, which can lead to more production and innovation. Similarly, reduced toll fees for EVs serve as a direct incentive by lowering the cost of using certain roads and bridges for electric vehicle owners. These incentives aim to make electric vehicles more appealing and accessible, whereas import tariffs do not fulfill this role directly.
