And another question, I hope you don't mind, but logically, why didn't Jack and Sara use the cable car to go down to Silent Valley and get to the cabin and escape?

The cable car is out of order because the resort is out of season.
During the early stages of development, I even considered an alternative ending where the player repairs the control panel and restores power, triggering a cutscene of Siren Head grabbing the cabin on its way down.
This is the reason why Jack hid here.
