I have no idea how realistic this will be, but my previous experience of living and driving in LA caused a level of stress that I have no interest in repeating. I already hated car ownership before the spike in catalytic converter thefts, due to gas prices, sitting in traffic, dealing with road rage from other drivers, insurance costs, the risk of your car getting keyed / stolen / broken into, etc. I've decided I'd rather pay a premium to Uber / Doordash in order to avoid all that.
I'm giving this plan 3 months to play out. If the lack of a car proves unrealistic, I'll probably relocate to NYC, where I know I won't need one. That's how much I dislike owning a car.
EDIT- I'll be living in East Hollywood, near Barnsdall Art Park. Looks like there are grocery stores, bars, restaurants, etc. nearby. I work remote, so I'm thankfully able to avoid daily commutes.
