As more and more people choose electric cars, the disadvantages of gas-powered cars clearly become evident to the world. Especially as winter comes, the cost of fuel in a gas-powered car is usually several times higher than what people spend on an electric car. More fuel being used means that more pollution will be created. Nobody likes a hazy day during which they can't see the sunshine. It can deeply affect our moods. Besides saving money for owners, electric cars have another great advantage because they can accelerate faster than gas -powered cars. I often see gas-powered cars can't overtake electric cars which makes their drivers crazy. Gearbox is not an essential feature of a vehicle. The purpose of a vehicle is to take people from one place to another within a short amount time. Saving time is an essential thing for every vehicle designer and they try their best to achieve. Maybe gas-powered cars would be completely replaced by electric cars in the next ten years. In fact, the thing from an electric car that can get most of my attention is its green license plate. It matches a car's colour better than other colours.
