You'll start out as a 26-year-old who's never left home, but that all changes when you buy (or steal) an amulet that contains the soul of a beautiful woman. She's a veteran taxi driver who takes you out of your comfort zone and teaches you the ropes of the profession.
Your car has plenty of features that you can improve. Are you worried about having an accident? Invest in brakes. Are you superstitious? Increase your level of luck. You like speed? Make your engine roar. No matter what your style is, your car will adapt. So get out on the street and show everyone that you're the best taxi driver in town! (Or second best, if you're feeling modest.)
