Haha! No you’re not crazy, but the suggestion to a Californian of not owning a car is complete anathema. It’s true that some places are a little remote and you may find it a bit inconvenient, but if you are walking distance to a supermarket, and there is at least some form of public transportation, then just renting a car for major trips could work I guess. Californian suburbia was built around the car, so you may have a bit of a battle on your hands. Good luck!
