I disagree. The article I linked suggests in NYC that Ubers are empty 1/3 of the time on weekdays. The problem of course is that no city is so mixed use that destinations are equally likely to be origins at any given time of day. taking labor out of the equation it will become cost effective to be empty an even larger fraction of the time (presumably humans stop driving when they're not getting enough fares to be worthwhile). It may also be economical for these vehicles to never park (not only because parking costs money or might be far away, but because it increases latency) for large fractions of the day.
