[Left 4 Dead] why didn't the l4d survivors team up with the l4d2 survivors?

1. The car didn't fit everyone.  

2. Nick, Coach, Ellis, and Rochelle were heading to New Orleans, because they heard there was still a military presence there.  In contrast, Francis, Louis, and Zoey were heading out by boat to the Florida Keys.  Neither side believed the other would actually make it to safety: Nick, Coach, Ellis, and Rochelle believed that their only hope was being rescued in New Orleans, while Francis, Louis, and Zoey's experiences on the military base taught them not to trust the government or the military.  With such sharply diverging objectives, the only thing to do was to wish each other good luck and then go their separate ways.
