@ebork the distance from your home to your "main job" which is your first ride is considered communiting miles and is not tax deductible. Same thing for the distance from your last ride drop off to home - it's commuting miles and not tax deductible.
does not matter if it is pre-booked or not.
look at the chart and explanation on page 12 and the horizontal line in the middle of the circle.

milegage from the first pickup and to the 2nd pickup are deductible because you are going between two business locations. look at the parts of the circle where is states "always deductible"
