An analysis published by MIT has found that Uber and Lyft drivers in the US only net around $3.37 per hour on average, and nearly a third are probably losing money after car costs.

A study [PDF] put out this week, and carried out by Stanford researchers Stephen Zoepf, Stella Chen, Paa Adu and Gonzalo Pozo, has found that nearly half of all drivers could actually claim that for tax purposes their work was a net loss.
