For my first car (2011), I was paid $1500 out of pocket, about $100/month in loan for 2 years, $40/month in insurance and about $80/month in gas, including out-of-town road trips and driving to airports 200 miles away.

That was pre-Uber, but last time I took an Uber in that town, it was about $10 one way for "short" distances (e.g. 4 miles to go to a grocery store - things are spread out in TX).

The car never had a high maintenance downtime (and only one fender-bender in the 7 years of ownership), and I can't account for maintenance; think it'd be under $80/month.

So we have about $300/month for car ownership, or about 10-15 Uber roundtrips/month. I'd say, there's no clear-cut conclusion here.

Plus it extends the usefulness of transit and working around schedules/connecting endpoints with stops, is great for health and fitness, and in many areas there's decent diverse social scenebuilt around different types of cycling. No better way to know your city.
