I found the same. "Worked" 4 hours Monday, 5 rides all to airport. I declined 3 and finally accepted 2...after taxes, fuel, commission, I'm somewhere around $3/hr for that day. Worked 3 hours Tuesday. 1 $13 ride before I calculate any fees. I don't even want to know. Then yesterday evening around 5-7 pm turned the app on for 2 hours while I parked in front of my house watching TV. No pings at all. Not 1 ping in 2 hours. Worked 90 minutes this morning, not a single ping. I guess I will try later in the day (I will need to nap, my normal bed time is around 9-10 pm), but the weekday mornings are a bust in the west from say Jones to Durango, Russell to Spring Mountain.
If it matters, my rating is 4.88 for ~60 rides and I verified my GPS and 4G is working perfectly. Rider app shows same as others have mentioned, every where I go there are several other drivers all on top of me. Hopefully the weekend is better/busier. I now wish I had worked alot more last weekend with fewer drivers on the road. Nevertheless, the residential problem should be solved, I didn't go anywhere near the strip today and anyone in the residential area where I was would have had a ride to their door in 2-3 minutes from me or any of the others hovering around. I personally used Uber as a rider on Monday night to visit a couple different bars to watch football and every pickup was less than 5 minutes, including one that was literally 30 seconds.
