OP, consider if you're a part time Uber or Lyft driver, not originally planning to drive at that time, what would it take to motivate you (and others like you sitting on the sidelines) to drop what you're doing and get into your car and sign into the service as a driver.
I don't have to like the pricing, and I really hate Uber's decision to make the surge pricing much more opaque (you now only get told the current price and not that it is surge and what the surge multiple is), but I don't begrudge the amount of surge in most situations.
I'm not a regular Lyft user. Does Lyft currently disclose the Prime Time multiple when it quotes you the pricing?
