I don't really understand why a taxi would be made as a 2 door coupe. I would think for most people, practicality would trump style on a taxi.
In places that are walkable/transitable, one of the only reasons you have to take a hailed ride is that there's four of you and the fee for the Lyft makes sense.
No of course not for the HNers who pull down 350kUSD/yr before options but y'know... normal people...
