Because it would be waste of time, effort, and money. Accidents like this don't happen enough to worry about.

But when accidents do happen, it's bad for the airline business (not to mention the loss of life, no matter how relatively small it is)
OK, I have the answer... Tom Tom Go! Lots of new cars have GPS navigation systems that show (and tell) the driver where he is and were to go. Why don't commercial airplanes use GPS nav systems on the ground at busy (and not so busy) commercial taxiways? I figured the technology in a cockpit is at least as comprehensive as an average luxury car. It's hard to get it wrong when you keep the triangle on the red line, plus an alarm can go off if you are off track. I mean come on, farm tractors use GPS nav systems to make pretty clean crop rows. Even single engine crop duster airplanes have GPS nav systems to help them provide even coverage with less waste.
