You cant get away, but if you think you have what it takes then here is some intel for you. After robbing a bank, either wait for just the one bank robber or all four to increase your money and begin your get away. Avoid cars and other hazards on the road while trying to pick up all the wanted posters to help increase your money. Pick ups will also help you to zip further much faster or just bust right through anything, but be careful because they only last for a limited amount of time.
