I'm sure it varies greatly from market to market, but Uber/Lyft are certainly facing some difficulties. For one thing, many drivers are eligible for unemployment and stimulus checks and would rather rely on those than run their cars in the ground for 50 cents per mile. It also doesn't help that both companies are charging riders much more, but not passing any of that along to the drivers.
Also, those who are driving have been doing a lot of food deliveries -- and MANY find they like those deliveries better than driving people. The hours are more normal, less wear and tear on the car, and most burgers behave better than drunk people.
Driver social media is full of stories saying "I'll never go back to driving people." Of course, that will change when the free money stops flowing and deliveries dry up as restaurants reopen and people start dining out again.
