Can you imagine what would happen if noone used their cars but took public transportinstead? Without a doubt, there are both benefitsand drawbacks to such a situation.
Finally, fewer cars on the road most likelymeans that there will be a dramatic reduction intraffic accidents. Consequently, there will be fewercasualties as well. On the other hand, using publictransport exclusively could raise issues of reliability,as services can be delayed or cancelled due to eventssuch as public holidays, transport strikes and so on.
To begin with, choosing public transport asan alternative to private cars will lead to animprovement in people's health. Those in favour ofthe idea support that a reduction in vehicles on thestreets will mean fewer emissions, which in turn willlead to less air pollution. Yet critics argue that relyingexclusively on public transport will cause the meansof transport to become overcrowded. As a result,travelling will become unpleasant. For example,there could be more instances of pickpocketing.
Secondly, using public transport instead ofcars will make life in cities more pleasant. Fewer carswill mean less traffic congestion and less noisepollution. However, moving around might becomemore difficult. Since people will not be using theirown cars and so will not be planning their ownroutes and schedules, they will be limited by publictransport timetables and routes.
All in all, travelling around using publictransport only has benefits as well as drawbacks. Itmay lead to a healthier, less congested and safer placeto live but it could also cause unpleasantness andinconvenience to travellers. Ideally, the use of carsshould be severely limited, but not banned altogether.
