Ok, after 7 seconds seems wierd. Do you have any other triggers that activate after 7 seconds that may accidently affect the cars becouse of insufficient conditions?

For the first trigger, why not have the cars just spawn in (Center of Up Outer Road right up <gen>) and related regions. The "unit has entered region" will effect units that are created in a region.

Actual come to think of it, do the cars have the ability 'wander'. Becouse that will make them randomly move around every few seconds.
