Flynt’s Hustler Club cab traffic

Door: Anthony Tockar

“How might I track a person? Well, to zone in on a particular trip, I can use any combination of known characteristics that appear in the dataset, such as the pickup or drop-off coordinates or datetime, the medallion or license number, or even the fare amount from a receipt. Being the avid fanboy that I am (note: sarcasm), I thought it might be interesting to find out something new about some of the celebrities who had been seen in New York in 2013. In particular, where did they go to / come from, and how much did they tip?

In order to do this, I spent some of the most riveting hours of my professional career searching through images of “celebrities in taxis in Manhattan in 2013” to find enough information to identify the correct record in the database. I had some success – combining the below photos of Bradley Cooper and Jessica Alba with some information from celebrity gossip blogs allowed me to find their trips, which are shown in the accompanying maps.

In Brad Cooper’s case, we now know that his cab took him to Greenwich Village, possibly to have dinner at Melibea, and that he paid $10.50, with no recorded tip. Ironically, he got in the cab to escape the photographers! We also know that Jessica Alba got into her taxi outside her hotel, the Trump SoHo, and somewhat surprisingly also did not add a tip to her $9 fare. Now while this information is relatively benign, particularly a year down the line, I have revealed information that was not previously in the public domain. Considering the speculative drivel that usually accompanies these photos (trust me, I know!), a celebrity journalist would be thrilled to learn this additional information.

How about we leave the poor celebrities alone and consider something a little more provocative. Larry Flynt’s Hustler Club is in a fairly isolated location in Hell’s Kitchen, and no doubt experiences significant cab traffic in the early hours of the morning. I ran a query to pull out all pickups that occurred outside the club after midnight and before 6am, and mapped the drop-off coordinates to see if I could pinpoint individuals who frequented the establishment. The map below shows my results – the yellow points correspond to drop-offs that are closely clustered, implying a frequent customer.

The potential consequences of this analysis cannot be overstated. Go ahead, zoom in. You will see that the GPS coordinates are terrifyingly precise. Using this freely-obtainable, easily-created map, one can find out where many of Hustler’s customers live, as there are only a handful of locations possible for each point. Add a little local knowledge, and, well, it’s not rocket science. “I was working late at the office” no longer cuts it: Big Brother is watching.
