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.
Base fare which is the price your Uber ride will start at, and that of course vary on what city you are in and the type of service requested. Cost per minute is the price you pay minute for the whole duration of your Uber ride. Cost per mile is how much you get charged per mile, again it varies by city.
