What is the primary danger of performing 'wheelies' or stunt riding on public roads in Afghanistan?

1. It is illegal, eliminates steering control and front braking, impairs forward vision, and frequently results in fatal loss of control
2. It is acceptable on a quiet road where no other traffic is present
3. It is safe provided the rider is wearing a helmet and full protective gear
4. It endangers only the rider, so it raises no question of public safety
