Ridgewood is a walkable, commuter town and has always been that way. Buy a home near town and you walk to your commute. Many do live within walking distance but choose not to for a variety of reasons.
When I moved to town it was a known quantity that parking near the train was limited, get there by 7 or walk. This was when the car dealerships were in business and there was no parking in Hudson street lot for commuters.
Lastly, even garagzilla would have been very very limited in number of commuter parking as it was always intended for shoppers and diners to support the CBD. The fact hat it could support many commuters would only be relevant if store employees and shoppers were unwilling to park 3 flights up to grab a coffee. And even then commuters who are so rushed in the morning would have to park on the highest level and walk over.
