car borrowing

My brother goes to SRU also. He has gone through many cars due to wrecking and accidents. Some of them were not his fault in his defense, like the time he was driving home from work at 5am and a horse ran out in front of him. However, my brother is a crazy driver and i am terrified to ride with him. he is epeleptic and extremely diagnosed with ADHD. This makes him not pay attention or get distracted easily. This weekend he wants to borrow my car since I just had it inspected and got all new brakes, tires, and other things. his car has bad tires and he does not want to drive to Pittsburgh with it. Im a little nervous about this, but I said yes. I want to be a good sister, but I really hope my car makes it home ok.
