The Boston anomaly and map is interesting. The requirements are a trip from 10pm-4am and a trip again 4-6 hours later. However, due to the MBTA shutting down around 12:30am and bars closing at 2am the criteria captures just about any partygoer.

So if you took an uber to some bar/club/friends at 10-11pm and again after 2am when all bars or the T is closed, you're likely counted. I doubt this represents customers having one night stands and is likely just a heat map. This is further explained by the small pocket in Somerville that is not accessible by the train, but by bus where people may opt for an uber.

That's not to say that there are no rides of glory or whatever the hell kids call it today.
