Oswald's Corner. Comments on recent. autism-related research reports. A Revised M-CHAT.

After the ride starts, Uber does indeed charge for waiting time. However, the charge to the rider is often less than the minimum wage, and what the driver gets is only 72% to 75% of that. For example, on an UberX ride here in Utah, Uber charges you $.11/minute ($6.60 / hour) for wait time. I would get $4.95 of that.
After you added up the four different variables, you calculated that your fare would only be $2.78. But in your area, the minimum fare for UberX is $4, so you will be charged $4 instead of $2.78. The base fare, cost per minute, and cost per mile vary city-by-city, and Uber service. Uber fare rates are different for UberX, XL, UberPlus, Black Car, and Select.
