The topic of transportation is a tough one because there are many problems related with it. Most of these problems have some influence over our health and they must be solved immediately. Therefore, if I have to decide if governments must spend more money on improving road and highways or public transportation, I would choose public transportation. My answer is based on the fact that healthy problems derived from public transportation are crucial for us.
Ok, let's see what mistakes you have done in this intro-
1. You have not introduced your prompt clearly and adequately to the reader.
2. Also you have gone a bit out of topic. (see the highlighted line above)
3. You have some words repeating too often
Let's do this intro as Pahan suggests above;
Roads and public transportation are two most important aspects in our daily needs. (HOOK) Some people argue that governments should allocate more funds for road development and public transportation should be looked at secondarily. (BACKGROUND OF YOUR PROMPT) However, I disagree with this view and believe that public transportation deserves more attention over the roads. (YOUR OPINION)
Also, make sure you include the prompt with your essay next time, for us to understand what it really requires from you.
