What do you call it when a cab driver takes you on a circuitous route to pad the fare? That is what Driver #1100 (medallion #0654) did to me (on trip #0136 around 8pm 09 Feb 2020). I took what was supposed to be a ~18 minute ride from the airport to my hotel. About 25 minutes in, I looked at the GPS on my phone and found us miles past my hotel (in the opposite direction from the airport). Bottom line: $71 and 36 minutes. Needless to say, I took an Uber back to the airport at the end of my stay: $21 and 18 minutes. Save yourself $50 and half-the-time.
