Shhhh... You're devaluing lyft and Uber stock with your arithmetic! /s of course you're right but this lack of accounting for vehicle depreciation (not to mention a very high liability risk for every minute on the road) is rooted deeply in American's sunk cost fallacy with motor vehicle ownership. It's almost a genetic instinct at this point and for every person who does the math and realizes it doesn't work out there's another who won't care
