-l2 and l3 are for the other textures , for example in g-track3 there is 
a permanent skidmark
on the whole track (-l2)
and -l3 for another layer , but the acc loader (and the grvtxtable 
class) in torcs is not ready for 4 layers,
-l3 is for futur uses

I don't know but may be here is some clues:
Only object in the layer 0 are kept in the result, that means that the 
-l0 file must contains all the objects,
and the objects MUST have the same name in all the layers..
the best way is to use your <track>.ac to generate <shad_track>.ac :
    accc +shad <track>.ac <track_shad>.ac
accc will generate a new ac file with a basic vertical mapping on all 
object.
and then use accc -g to combine all the layers. (don't forget to create 
the shadow2 texture).
