I mean, I hate to say it but I always think Uber does a great job.

The UX does what it needs to do, and gets ahead of tasks you need to complete as you go through the process. The nailed the standard ride experience.

- Open app, "Where you going"
- "Heres the rate"
- Pick
- "Hey, your driver is here"
- Ride
- "Hey, you want to tip in advance?" 
- End journey
- Next time you open the app "Hey, how was the last ride"
- Rate
- Repeat

The happy path is a well oiled machine, Id say this is an examlpe where I almost forget about the UI even exsisting.
