. Although electric engines are not so widespread, more and more people consider changing their gasoline-fueled vehicles to electric cars. And this choice is more than reasonable. The maintenance cost of electric cars is lower than the one of those fueled by conventional gasoline. Fuel prices heavily depend on the political and military situation in countries providing oil; even if we do not take it into consideration, one year of driving a gasoline car would cost you about $2,100 (given that you drive about 15,000 miles per year, spend one gallon of gas for each 25 miles traveled, and buy gasoline at $3.50 per gallon).
