Everyone has experienced those situations where your transportation was critical but you'll be too busy/groggy/otherwise distracted to make sure you get picked up in time to get where you need to be!
For example: You have to make an early morning flight when your friends & family are sleeping or at work... or you're positive that rides will be near impossible to hail at a certain day/time, but you'll be needing one regardless! (Did someone say New Years?!)
You'll soon be able to reserve a standard Lyft or Lyft Plus car service through the app in basically the same way you currently hail rides, only now you'll see an additional option to pick a specific time within the next 24 hours for the driver to arrive at your pickup location.
Lots can change in 24hrs! So if your plans fall through or you need to modify the pickup time or location, you can easily do so through the app - up until you're within 30 minutes of the set arrival time.
The scheduled ride feature is currently being beta tested in the San Francisco market. Despite the ongoing testing, substantial progress has been made as the kinks are being ironed out - and they already plan on rapidly expanding this functionality & service to many of the other current cities with operations!
