I don't know but Uber has proven to be a shinny example of a ponzy scheme within a larger ponzy scheme. They will never be profitable, Burning billions, so is the case with Careem whom I met, and their staff was at loss to tell how this is a viable business to run. They disrupted taxi drivers, making good earnings. They benefited a lot to consumers eliminating overcharging by common taxi drivers. But as an entrepreneur I am still failing to understand how far they can go before they run out of fuel $ eventually.
