Skin of Your Teeth
- Exit the car just before the train hits
Timing this objective is pretty difficult. You need to leave enough time for Trevor to get out of the car and jump out of the way. You need to time it so the train hits just as you step out of the way. It may take a few tries to time it exactly right. Even when you think you have it, the game will not necessarily count it. Jump out just before the train reaches the traffic-light post.
- Kill Al Di Napoli using the train
This one is easy. Just ignore Di Napoli’s pleas for mercy and drive him to the train tracks. Leave him there so the train smashes into the car and watch it crumple under its force. Who doesn’t love a good train crash?
