Drive the rescue 911 car as fast as you can and follow the directions. GO back to the police base and park in the shown spot, being careful with the peasants. Use arrow keys to drive and space bar to stop.
Manage to bring those cars with bombs to the special teams, using the right and left arrows of the keyboard to keep the balance, the down arrow to brake, and the spacebar to jump. If you do pirouettes, you win more time...
