主题：车祸和由车祸引起的思考 -- 好风长吟

All you ever think about is yourself and your parents. You never think about those other lives under the formidable threat of your crazy drive!

So my answer to your question "是因为我没有责任心么？" is: (1) YES - you're a very irresponsible person; or (2) NO you're not an irresponsible person, but you're very SELFISH. You can choose whichever you like. A person who asks such a question after three great dangers caused by his own irrational behavior doesn't deserve any better judgment. Sorry for the harsh words..
