I'm apparently getting the ass end of Lyft's Power Driver Bonus guarantees: $ 90 for 50 rides/inc 30 peak with 90% acceptance, $ 185 for 80/35 and $ 270 for 110/45. I never make anything with a 90% acceptance rate. I guess they don't love me the way they love you.
Yours are better, aren't they? Lyft is guaranteeing you a real payout.
What I get are "guaranteed weekly amounts". If I drive X rides, Lyft guarantees I make Y dollars. But that Y requires that 90% acceptance rate AND EVEN INCLUDES TIPS! So basically, Lyft has their actuaries, market pukes, and mathematicians figure out statistically what would be the number their average driver would make and then guarantees that to us more or less.
Their goal is to get drivers on the road driving for them, not Uber, to get drivers to pick up all rides even those far away, and to pay zero.
When they send me their guarantees, I read that as, "my best guess is that if I drive for Lyft and hustle, I will make Y dollars in X rides and Lyft will pay me nothing." If I think I would likely earn less than Y, I take them up on their bet and drive, but because of the 90% acceptance requirement, if I make the X and Y combo, the rational strategy is often to turn Lyft off and Uber, to turn the paper gain into a real gain while earning through Uber.
