I think facebook events is more catered towards events i.e weddings, parties etc and not the weekly casual hangouts we do with our friends. Moreover I haven't met a lot of users who actually use it despite it being around for a long time.

About your question, the user doesn't have to enter any information for ETA. The app calculates that based on the hangout destination and your current location.

well in that case have you considered the battery usage? I mean doing even the simplest mapping in the background could drain so much of battery life.

We have worked on making the tracking part as efficient as possible(code optimizations). Also the tracking will be on for a very limited time 45 mins to 1 hour(around decided time to meet) and the interval for location updates will not be very small hence helping in battery preservation.
