I think I'm ready to drive home alone
Are you sure that you are ready for that?
You know, it's gonna have to happen one day and my parents would want the same thing.
It sounds like you might be a little bit nervous about. You should make sure that you have a way to reach someone in case something happens.
It's okay if I run off the road or crash into a tree, I can rebound and you can't change my mind.
Well make sure you drive carefully. Not everyone rebounds so easily from a crash. If you get too nervous you should pull over and call your parents for help.
