Nah, that’s not it. I drove for both in a major city in the months before the virus and outside of peak hours Lyft always has substantially longer pickup times. This is based on a few hundred rides for each company. This means that they have fewer passenger per driver, so the biggest delta is a smaller user base. Once the lockdown began Lyft rides basically evaporated overnight, while Uber was still going strong at certain times and certain places, catering to essential workers. But both are worthless as a way to make money right now.
