"because GPS simply ain't happening in New York City."
Portable GPS units may have this problem. However, vehicles with integrated GPS units also use sensors on the wheels and steering to correct for areas with low signal. My 6 year old car with integrated GPS is dead accurate crossing the tunnels (it even shows when I crossed over from NY to NJ, corresponding precisely to the point it's indicated in the tunnel). Navigating NYC has never been a problem either. I'll stick with the factory options I guess.
I had an Infiniti FX 35 and the dead reckoning never really worked well in the city. With the tall buildings in midtown, it lost GPS quite a bit and it even thought I was driving on the hudson river once and not thru Lincoln tunnel! Apparently I've also taken my car to the top of the empire state building and through madison square garden. Once I get to the village and downtown areas though, it works fine and that's where you really need GPS since the streets have actual names.
Guess it depends on the car and how well the system is implemented.
“An engineer explained to us that hundreds of ear impressions were gathered in the name of research, and while each one obviously boasted its own unique shape and size, one single characteristic remained uniform across the board: the entrance into the ear canal is not a perfect circle, it's an oval.”
