I can afford about four trips to downtown in an Uber for the annual cost of my car insurance, registration, and parking, but sure
You're well below average if that's true. AAA reports the average annual cost to own a car is around $10,000 - that's all inclusive - purchase, financing, insurance, maintenance, parking, etc.
In my area, an Uber trip from my house to the grocer, my office, or the local school is $10-$15.
