What should you do if you get boxed in while driving on a one way street?

If you are driving on a one-way street and get boxed in, keep driving in the same direction the others are going. Eventually, some of those cars will 'split' from you. You can always later take a few side streets(turning corners and such to get going the opposite direction), flip on your turn signal and hope that the other driver notices that you're trying to move and allows you to move.
