So all of Rick's stuff has been stolen, and the last thing to go is the garage (the garage is actually lifted by a UFO/claw machine and flown away). Rick has a tracker device thingy on his watch and determines his stuff has been 'repossessed' by some dudes he owes money to.
>"**urp** intergalactic b-b-ingo Morty, not even once".Since the portal gun was inside, he can't just warp there, but has to travel by car to get it, all the way in [somewhere else].
>Gee Rick, won't we have to fight a bunch of aliens with your stuff?>Jeezus Morty, you've seen how many lazers I have as security, they're all dead now, even if the nerve gas didn't get them. Family road trip, and Rick offhandedly mentions that his inventions are worth billions, and only the family is on the white list. Whoever gets there first could potentially lock everyone else out. Start the competition.
Rick's racing because it's his stuff. Morty's riding with Rick because he wants to keep the status quo, and for all his faults, knows Rick is the only one who should be handling that stuff.
Summer's going it alone because she wants independence.
Beth and Jerry are riding together because they want some leverage over Rick and control of their own household back, but separate partway through when it's revealed Jerry wants something to hold over Rick, and was planning to double cross Beth last minute to become the real 'man of the house'.
Jerry and Summer end up teaming up, provided Jerry gets the credit and Summer gets the actual money.
Wacky Races hijinks ensue.
