There are some advantages and disadvantages f having only free public transport in cities.
On the one hand, the use of public transport helps the environment to avoid the car’s pollution. It also helps to improve urban mobility avoiding traffic jam.
On the other hand, some disadvantages are:
- Sometimes, the transport is saturated so you are not allowed to get in.
- Poor hygiene.
- You have to pay if you want to use the transport wherever you go.
To sum up, I think public transport would make a better mobility in the city, despite all disadvantages, it is good for our travels.
