Oswald's Corner. Comments on recent. autism-related research reports. A Revised M-CHAT. A paper by Robins et al. appeared in the January 2014 issue of the journal Pediatrics, reporting the first. published data for a revised version of the Modified Checklist for Autism in Toddlers (M-CHAT) screening.
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.
Uber charges are based on a combination of time and distance. If the car is travelling under 11 mph (18 km/h), you will be charged by the minute, and if you are travelling over 11 mph (18 km/h), you will be charged by the mile. You will also have to pay a base rate, that varies by location.
