> Uber has a lot of data, but even they don't know total hours spent before or after shifts in prep for work nor expenses with regard to vehicle maintenance. I would think Uber has exactly the data they would need to calculate this meaningfully, or at least the points you list aren't the decisive shortcomings. Most jobs require that you get yourself to work and prepared (to some degree, at least, but one that seems to apply fine to Uber drivers) on your own time. Also, in the blog post they state that they agree with the methodology around calculating cost of vehicle use, which regardless is not an area of great contention. There are stable and largely uncontroversial numbers published by tax authorities, and there are rental agencies that provide vehicles at fixed rates.
