Also, as I mentioned in another comment, it's just rides to work in the morning. I take public transportation home after work.
I keep track of all my numbers. For the 86 months I had my last car, I paid an average of $236/mo.
This includes purchase price (subtracting out the amount I sold it for). Insurance. Taxes/fees. Gas. Auto insurance. Repairs and maintenance. Silly things like car washes.
Of course, I didn't buy a brand new car, or even a recent car. And bought a reliable brand so repairs were low. My insurance was not just liability. All apartments I lived in had parking, as did my work. The types of apartments that have expensive parking are the type that have high rents anyway, so I save in both by not living there.
Excluded is the gas for road trips, but I think that's fair as I doubt you used Lyft/Uber for road trips.
So for less than what you're paying a month, I got to have a car, and got to drive anywhere I wanted to - not just work.
It's quite affordable starting at ~$350/mo, so I am curious to see how people will accept it.
I'm not sure whether you're referring to driving under the influence or merely about parking. If the latter: In most cities in the US, these are mostly non-issues. So I disagree with your use of "most". Although I've used Lyft in the last few years for various reasons, only once did I use it because I was worried about not finding parking. For other occasions, I used public transit. But seriously - probably less than once a year do I need to find alternate transportation because I'm worried about parking.
(BTW, I forgot to add parking to the above estimate. I spent on average $6.03 a month on it).
You can see my numbers here for my Civic.
Mine was 8 years old when I bought it, but with low miles (about 60K). So I paid a bit of a premium - almost as much as the 2014 Civic on that page. I kept it till it was at 144K miles. Effective cost to own was under $300/mo.
Comparing the 2014 numbers with mine:
Insurance is almost the same.
Repairs + Maintenance was less than a third of their estimate. I didn't skimp at all on this, BTW. I'd be worried if a 5 year old Civic has that many repairs!
No financing - paid in cash. Even the 2014 one is a little over $10K. You can just save and pay cash.
Their estimate requires a lot more in fuel costs. Mine is about two thirds of their estimate. This can be highly variable (e.g. if you have a long commute).
For example, let's say you bought your car for 10k, then sold it 7.1 years later for 9k. You have 1k of depreciation. You also have $6,300 at 7%(a typical target rate) in lost income from not keeping that money in a productive asset for those years.
In my case it came down to $242/mo vs anywhere from $360 to $480/mo with Uber. It's not clear to me that had I invested the purchase price the 7% return would be enough to make up the difference of $120-240/mo. Certainly not in the first year. I'd have to do the math to see when the breakeven point would be where that initial investment is yielding more than the extra cost of using Uber.
There's also the fact that 7% is the market's return, which is over a 30 year span. On a 10 year span, the rate of return is highly volatile, and could even be negative (on the flip side, could be a lot more than 7%).
I just ran the numbers, BTW. With my purchase price, invested at 7%, I break even after 7 years (just about the time I owned it) - assuming Uber is the upper bound of $480/mo. At the $360/mo cost I'd break even after 3-4 years.
I didn't take into account the sale price, so that would make the breakeven point a little farther.
... for someone living in a bubble completely disconnected from the planet Earth, where they think that a $400/mo parking spot is 'normal'.
Sure, there's a few million people like you out there. Not enough to make Uber break even, though.
It's great that you get free parking, but have you considered that you're living in a bubble too? 6 out of 7 people globally don't even own cars!
But I'm also a wealthy techie who happens to live within spitting distance of a booming downtown. 90% of the people living in my metro area (Seattle) do not pay $150/month for parking (And I'd wager that 99.9% do not pay $400/month for parking).
... And most of those people have commutes of >4 miles. The problem with taxis is that you pay by the mile. You'd be an idiot to drive yourself to work, if you live 2 miles from work, and have to pay through the nose for parking. You'd be an idiot not to drive yourself to work, if you live 15 miles from work, your bus system sucks, and your parking is cheap or free. 
Doing 15 miles/day in a taxi costs nearly 3x that of doing 5 miles/day in a taxi. Doing 15 miles/day in a car is pocket change, compared to doing 5 miles/day in a car (Or 0 miles/day). Most of your costs with a car are fixed. Most of your costs with a taxi are distance-based.
 And if we're going to get into a discussion about how the world should value the cost of parking spaces, I will happily point out that what we should have is good bus services, not private chauffeurs.
A lot, but typically not most - I drive about 12k km per year (16 km commute 2-3 days per week) and over the past six years my fixed costs have been around $7k. My variable costs have averaged $0.26/km for about $16k total. (All CAD)
