It's roughly a $50-$70 ride for me every morning to work. That already puts me over triple my car payment. The other random trips to the store/etc would be far cheaper, thankfully, but depending on usage I can't imagine it being less than my gas costs in a month (roughly $50/m). There's still repairs/insurance/licensing/etc, but I doubt they're costing me the $700 extra that just driving to work would be costing me via taxi.
The problem is I don't live in the city, so my distances are greater, and tend to be very anti-taxi.
I actually want to take an uber to town on the weekends so I can drink/etc at dinner, but I usually don't because of how expensive it is.
Mind you, I don't think it's unfairly priced currently - but that still doesn't make it as cheap as I'd need it to be to use all the time.
