I think that was what she was using, since it relied on people inputting traffic data. She swore by it, but every call it made was bad. If I listened to it, I'd still be driving to that meeting a month later!
It told us to go from the LIE to the Northern State Parkway, when in my view the LIE traffic was normal, but I humored her and went to Northern State, where the traffic literally stopped. You could see the LIE moving fine through the trees.
Then we were driving down Broadway, the main thoroughfare going downtown, at the center of Manhattan. It said to go to the FDR, which was half way across Manhattan. I speculated it would be packed too and stayed on Broadway. I could see construction up ahead on the next block. It took awhile, but we got through it. Then she said, now its saying the FDR's backed down. That's what I figured would happen. If one road's backed up the cars go to alternatives and they get congested, so it's often better to stay where you are and not go back and forth.
I just have a feel for the local traffic from years of driving in it. But I don't know that I'd want to be using that thing in an unfamiliar place, either, as who knows where you'd end up. I like to stick to the main roads.
What I'd really like is an app that tells you the neighborhoods to avoid when you book a hotel. Sometimes user comments help on hotels.com, etc.
