Trams, as a new type of transportation, have attracted much attention in recent years. However, despite all the advertising and publicity, trams cannot replace gasoline vehicles as the mainstream mode of transportation. First of all, there are many limitations and shortcomings of the tram, which make it unable to meet the diverse needs of people for travel. Secondly, the cost performance of electric cars is far less than that of gasoline vehicles, which is one of the reasons why many consumers are hesitant when choosing. The range of the tram is an issue that cannot be ignored. Currently, most trams have a range of around 200 km, which may be enough for a daily city commute, but when it comes to long journeys or special needs, trams become inadequate. In addition, the charging facilities are not perfect, which brings a lot of inconvenience to car owners. In contrast, fuel vehicles do not have such troubles, gas stations are all over the place, and the refueling process is relatively simple and fast. From the point of view of price-performance ratio, the tram is also quite inferior. Although the purchase cost of an electric car may be lower than that of a combustion engine vehicle of the same class, the maintenance cost and overall cost of the electric car are higher than that of a combustion engine vehicle. First of all, the battery life of trams is limited, and replacing batteries is often expensive. Secondly, the spare parts of the tram are also relatively expensive, which makes consumers need to think twice before buying an electric. To sum up, although the tram is an environmentally friendly and energy-saving means of transportation, due to its many problems and shortcomings, it cannot replace fuel vehicles as the mainstream means of transportation at this stage. For those consumers who are looking for practicality and efficiency, buying a fuel vehicle is still a more sensible choice.
