Could these trucks be removed or moved away from the wall there? I don't know when or why they appeared, but they make it way more difficult to go up the wall and over into the driving school area from the warehouse side.
I think it would also be better to make them Packers (or at least one of them). Packers are underutilized, I think partially because they are pretty scarce. Adding more Packers in general (particularly near areas with lots of stunting potential and/or in such a way that they function as jumps) would also be nice.
