(correction please) Young people shouldn’t be allowed to drive until they are 21.
I completely disagree with this. The minimum age to obtain one's driver’s license shouldn't be raised to 21. 21 is too high an age. Driving provides a way of transportation to go to places like university, work, and after-university activities that would otherwise have to be provided by a parent or friend, putting more work in their hands. I also think that when we are 18 years we are already responsible and we need more freedom and independence. One of the main advantages is that if it's happens something bad happens at home, or to our parents, we can take the car to try to solution solve it. On the other hand, I think that the a problem is that there are some people who don't understand the rules of the road. That goes for teenagers, people in their 30s, 40s, 50s, and so on. I know people who are 14 years old and are better able fit to drive than most 18 year-olds. Not only does the age not matter. Age is not the only thing that matters.
You write nicely. It is easy to correct because there aren't that many mistakes.
