After recent mentions on Gothamist and Kottke, this blog -- by a female cab driver occasional photos -- has been attracting a lot of readers, me included. "M.P." has some great insights into the life of the 24-hour city from behind the wheel; she has to put up with a lot of the crap dished up by "fares" of all stripes as well as by fellow drivers and hacks, cops, thugs, inanimate obstacles, etc.
She even offers some tips on tipping: At least a dollar for fares less than $10. 15% to 20% thereafter. More for nice service or waiting curbside. And it's easier to give drivers the fare and tip at once, instead of asking for exact change from the fare, then handing them back the tip.
