I have some bad driving habits but I can't change them.
Why can't you change your bad driving habits?
I like the way I drive and I'm set in my ways.
While we all have our own driving styles, it isn't appropriate to drive recklessly as it could cause an accident on the road and hurt others. If you have some weird driving habits that can affect others, it's wrong for you not to change them since it can hurt other drivers. You should try taking a defensive driving class to learn proper driving etiquette and to lessen the chance of an accident occurring.
I've never had an accident and I'm sure I won't have one in the future.
You can't say that you'll never have an auto accident if you have bad or dangerous driving habits. Try to modify your driving so that it's safer and less risky. Try to keep yourself as calm as possible when driving and stay focused on safety.
