@virjonbrahimllari - you don't understand how the IRS works! While Uber may track your mileage from the time the driver goes online, that doesn't mean they are all deductible. The IRS makes the rules on what is deductible - not Uber.
look at the illustration on page 12 of this IRS publication
https://www.irs.gov/pub/irs-pdf/p463.pdf
across the middle is a line from home to main job "never deductible". that is the point that from home until an uber driver picks up the FIRST client is 'never deductible" (and same thing for last client to home.
