Last Sunday I witness a traffic accident on my way home. I was wandering down the sidewalk while there went a loud crash. Two taxis crashed into each other about ten meters far away. I went up and found the two drivers bad injured, bleeding and trap in the taxis. Luckily, they were rescued on time because people came to help them and called an ambulance. As was clear that the taxi drivers were so eager take more passengers that they drove too fast. It reflected their lack of concern for the safe of both others and them.
