You can usually stack the "chores" as well. Run 2 races at level 3 in the bundle car and you've done all 3 of the tasks on the left of the Main Stage. Run 5 Escapes in the bundle car and you build toward the 12.5 miles (20km). The 3 in the middle have to be done separately but one is always the Custom Show car entry anyway.
My only real gripe about the tasks is the fact that doing Summit feats in the bundle car doesn't count towards any of the tasks.
In FH you get daily tasks on top of the weekly ones as well...
