I am a rather infrequent user of Uber/Lyft and have a question regarding a ride later this week.

I need to go to SFO airport from a somewhat remote East Bay location around 4 AM in the morning. Are these services likely to have 'Surge' pricing (e.g. due to there being fewer drivers at such hours)?

What are the chances of a driver accepting the ride and then canceling before he gets to my location because some other more lucrative opportunity comes his way?

Which of the two services is likely to be less expensive at that hour?

PS. I am told that at this particular East Bay location, cabs are hard to come by at the best of times!
