If you leave a fight, you've lost it. And the rules for loosing the fight apply.
This doesn't matter if you cruise, thrust, engine kill, or bloody swim your way out, if you leave you've lost. If they -chase-, now that's a different matter. It's still a fight, so you may turn around and keep fighting. If they don't chase, then you're gone. No turning around and hitting them again. Wait the cursed four hours.
-LOCKED-
This is the real true story of rock and roll; it was not about anything more then, how to live your life, as a gangster, in sartorial splendor, and turning the world into a place where normality would never return again...- Malcolm McLaren
