I have a feeling human operators are there for more customer service purposes. Given the location selected it might be wise to have staff on hand. The idea of no humans makes me think of the news story recently on the front page here about the hitchhiking robot being destroyed also seems relevant, although private areas may be less prone to incident like this. (https://www.wired.co.uk/article/hitchbot-usa-vandalised-phil...)

Also according to this techrepublic article, while level 3 may still require a driver, a level 4 vehicle can still be limited to the "operational design domain". So human drivers can still be in place for extreme edge cases. Although I don't know the specifics of these vehicles, and don't think the "levels" of driving are very useful.
