Lyft's pre-book is even worse. They do assign you a driver when you pre-book, but then you're beholden on that driver to still be driving when your booking time arrives. I pre-booked a ride to get to the airport at 4AM, figuring prebooking is the best way to make sure I had availability. Driver accepted it at 9PM, was not awake at 4AM. The Lyft app made me call support to cancel the pre-book and get an on demand ride. I couldn't cancel even though my driver wasn't active.
