[Rick and Morty] Why does Rick have a car and a portal gun?

I'd imagine having instant teleportation to anywhere in the multiverse would diminish the need for a car.

Portal gun runs on something. Presumably it might actually be really expensive or difficult to charge easily. He might have limited resources of whatever powers it. 

Plus Rick isn't always going out to a specific destination, he likes the journey and enjoys things like looting (Auto Erotic Assimilation), and random detours onto other planets (Look who's purging now). 

You play fallout or elder scrolls or a game like that. Do you always fast travel to your destination or do you enjoy going off the beaten path sometimes to see what you run into? Sometimes the journey is even better than the destination.
