Because of climate change issue, many people, including governments, discuss the idea of banning private motor vehicles in city centres. Governments want to control the number of cars entering their city centres in several ways. However, some people have some arguments against the policy.
There are two advantages in banning private motor vehicles in city centres. First, this policy perhaps leads to reduce pollution in the city centres. Gas emissions from motor vehicles bring about pollution. Only public transportations could enter the city centres. As a result, gas emissions can be reduced. Therefore, it can reduce pollution. Secondly, banning private motor vehicles in city centres is frequently an effective means of minimizing traffic jams. People can use public transportations only, thus there are a few cars in the city centres. Consequently, there is no traffic jams.
On the other hand, there are two major reasons against this form of interdicting private motor vehicles in city centres. Firstly, not all the destinations might be reached by the public transportations. If people want to go to a certain place, it is a problem if there are no public transportations to go there. As a consequence, private motor vehicles are still needed. Secondly, uncomfortable public transportations are likely to lead to people using private motor vehicles. People prefer to use more suitable ones than others.
Overall, the arguments against banning private motor vehicles outweigh the arguments in favour. Governments should improve the public transportations first, so people prefer to choose them than private motor vehicles. As a result, banning private motor vehicles in city centres is usually an effective solution for climate change issue.
