6 cars ?? Really ???!

In the episode where all the "Adults" go see Alex in her rich hotel (s11e10 Prescott) they all take their own car, am I the only that infuriates ? Didn't they know about carpooling ?? I mean, I'm french maybe the culture is different but, OMG I'm so angry each time I see it ! 🤣 I know it's mostly for the scenario but does it represent LA ?
