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