The reason I asked it because taxis have very different usage pattern than regular cars -- there might be extra operating costs (like extra gas, oil change, & service costs due to the extra range, and probably taxi operating license fee) that I'm not aware of which might weaken the analogy with the average car a bit.

Yeah, I'd not calculated fees or licensing. But other than that I'd still expect the costs of employment to be the highest, by a very large margin. Even if you replaced the entire car yearly, salary is still a higher cost.
