Financially, I'm not sure that I actually 'save' money. I live within 100yds of a ton of bars and restaurants, and a 5 minute walk to Trader Joes/Metro. I Uber most places but also take the Metro to DTLA and Santa Monica pretty often.
The whole car payment/insurance/gas/maintenance costs for sure are more than what I pay to Uber/Metro but what I'm not sure how to value the 'cost of walking.' I definitely pay a premium for my location and I often wonder, if I lived in a less convenient area (had to drive to groceries, far from Metro) if I'd be able to not have a car. Because as it stands, car costs < uber/metro/rent premium
