Discuss at least 2 reasons for the change in this scenario: Early suppliers of more fuel-efficient cars were able to charge premium prices for them, but that ability faded as other suppliers adopted similar technologies.

Technology has definitely changed with the fuel efficient cars. I just found out that cars are fully electric, which I think may have a cleaner air effect, but much harder to maintain. I would not want to have to worry if my car ran out of power and how far until I find the next plug in. Those cars became more popular because of the cost of fuel and the fuel efficiency it provided. I like the fact that you can decide if you want to use electricity or gas. Now that more charging stations are available they are more convenient to operate as well as the carpool incentives for purchasing specific models. As gas prices increase they become a sound purchase, but previously electricity was through the roof when charging these cars,but the use of solar energy solved that issue. Also the use of the free charging stations are a benefit, but it requires a tremendous amount of discipline.
