the reserved spots are for execs that have duties that require them be in ideal places, as we typically run our duties out of our pits to avoid running around the pits to help others. you will also notice the reserved areas are typically occupied by exec every race round. it keeps things consistent for the riders to find exec. if an exec members ends up getting pitted at the back of the pits its a time restraint and a hassle if they are required somewhere near track.
for example:
shane and eric are riders reps. easiest to keep them up front near the track.
Owen: does the BBQ by his pits, makes it easier to not have to wheel the BBQ around.
Myself: I do registration pick ups, transponders and other reg items from my pits.
