Cost to drive my car per month is, ready for this....
$450-$500!!!!!!!!!
That's car payment
Gas
Insurance
Your cost is MUCH MUCH higher than that. Parking, maintenance, depreciation. Never mind risk-based costs because it's almost without doubt the most dangerous activity you engage in recently (not true if you're a crab fisherman trading in the off-season).
The cost of parking is of course dependent on where you live. If you live in an large urban area, it's probably somewhere in the neighborhood of $200 per month--and is pretty easily derived from pricing in the secondary market. If you "drove till you qualified", you probably pay more than that when you consider the value of lost time driving to work, the additional maintenance on rural vs urban property, and additional gas to drive further and additional trips taken because few services are close enough.
In 2013, I actually worked out what owning a car would cost me (in central Denver, no less), and for a 1996 Honda Acord that was fully depreciated. Without maintenance included, it was just shy of $600. If you paid $36k for a car, and it depreciated like a house, that would add $100 more to the monthly cost (but in reality, we know cars depreciate MUCH faster). If you paid less for a used car, you'll get lots back in depreciation, but add lots in on maintenance. Tires, oil, timing belts, and other ordinary maintenance probably adds another $25-50 per month. Unexpected maintenance is dependent on the age of the car and will largely offset depreciation.
I'd expect the ordinary American is somewhere in the neighborhood of $1,200 per month for the privileged of owning a car when you take into consideration what else they have given up for that car ownership...specifically additionally owned / rented (and otherwise unexploited) real property allocated to parking considerations, lost time, decreased health (due to less walking / biking), lost wages due to auto injury.... $30-40 a day goes a long way to paying for a Lyft. Never mind this car ownership trade off is never considered in the light of "every trip by my personal car" vs "every trip in an Uber"; other modes of transportation will of course be factored in.
The question is actually a bit more telling from the Uber drivers' side...their wages vs their costs. And I'm not sure that figure is even positive.
