I believe that the reason Lyft and Uber are desperately trying to bring back drivers is not to meet demand, but rather to bring down the fares. The rides are so expensive that riders are simply not using them. The companies can only cope with this by having too many drivers.It has always been the case that if $(Lyft)$ and Uber were to charge enough to cover the cost of the product, many fewer people would choose to use it.They will never make a profit.$Uber(UBER)$
