Taxis are incredibly expensive compared to a car on a per mile basis. $1.00 is considered pretty cheap for a taxi while owning a Honda Civic averages out after all costs to around $0.35 per mile if you drive 15k per year. Now spread the registration, property tax, depreciation, and maintenance among 5 people and that cost is down to $0.17 per mile for 75k miles per year. I got these numbers from Kelley Blue Book if you're interested.

So in the end, you can run a 100% margin on top of the overhead of the car itself and still make fiscal sense for consumers.
