Topic: Should governments spend more money on improving roads and highways, or should governments spend more money on improving public transportation?

Traffic problems are a very important issue for governments. Because most of the traffic infrastructures are made by the government and they are in charge of traffic conditions in countries. Their policy direction may affect people’s behavior. For example, if the public sector chooses to improve roads and highways, then people may tend to drive their own car because they can drive smoother on the road than before.
In my point of view, I (you already said "my" don't say "I") think that (you already said "in my point of view") the government should spend more money on improving public transportation. By improving public transportation, it (you need to say "who") the government can encourage people to take bus or subway instead of driving the by car. It will not only provide an economical commute way for the person who does not have a car but also reduce the emission of carbon dioxide (change to "carbon dioxide emissions") from cars. Also, more and more people taking public transportation means that we (you have not been referring to yourself as the government, so use "they" or "the government") do (future tense, "would") not need to build so many parking spaces for cars drivers (the spaces are for "cars" not "car drivers") so that our ground can be used for other purposes such as building new schools.

Excellent job overall!
