The real allure, from a spectator's point of view that I would assume holds true for the drivers too, of these types of events is the surreal mixture of motorsport and the trappings of municipal life, a juxtaposition wherein commuter traffic is replaced by the sharks of Formula 1 but the localtabac in the background looks the same as it always has. It's sort of like spotting a supercar "in the wild"; the contrast of civilian cityscapes lined with tire walls, the complex acoustics that come from racing engines echoing through the lattice of alleyways and apartment blocks, it's just different from dedicated circuits with miles of run-off and gravel.
With the increasing chances of a Miami Grand Prix joining the Formula 1 calendar next season, it looks like such events are thankfully far from dying out even if Baku doesn't make the cut in the future, though plenty of other terrific street circuits have fallen off over the years— Montjuïc Park, Detroit, Adelaide, more—as the politics, safety, and finances of the sport shift over time.
It's only natural to add and subtract locations to keep everyone interested and well-paid, so if you aren't a fan of Miami, where would you place the next street circuit for motorsport's top flight series? Of course the considerations of shutting down a major metropolitan hub like central Paris would be a logistical migraine, but damn, wouldn't you like to see Vettel and Hamilton duking it out with the Champs-Élysées?
