I actually prefer taxis if I'm in Manhattan because it is about 10x faster to hail one of the many taxis rolling by than it is to wait and watch on your phone your Uber driver slowly make its way to you.
>A poorly designed (non existent?) tracking system, in which the taxi that I've requested may, in fact, be service another passenger, and have no intention of coming directly to me for the next 30 minutes. Or, never at all.
In New York, the cab's center lamp is lit up when vacant and available for hails.
>Almost no feedback, and certainly no "default opt-in" feedback mechanism on the driver, providing no incentives for the drivers to behave professionally or courteously for every ride, resulting in frequent rude or abrasive customer/rider interaction.
Tipping is the main incentive. Reporting of bad behavior goes through 311 (in New York). If you pay via credit card, the cab's medallion number is even on your receipt, so you don't have to remember it when you're in a huff leaving the cab.
I'm not saying the taxi cabs are the best system, but I want to quell misinformation.
