Discount the abundant people in the pictures. The only time there will be this many people walking there will be immediately before and shortly after a venue.
The spaces illustrated provided no other reason for anyone to visit, other than to attend a game. People will enter and exit the space in waves, with little or no desire to spend extra 'cash' above ticket prices Most of the time, the space will be vacant, and, very well policed.
In picture one, I see a large road running parallel to two huge venues with a ice rink pasted in. How convenient would that be to visit?
In picture two, I see a wildly unlikely peopling scenario with a smattering of tents suggesting some kind of "Taste of LA" thing. Perhaps 75 people are pasted into the space, in front of a facility that seats 10s of thousands, that when the venue is used, would dash through the space like a dust devil to disappear to cars, etc. (Besides, on the left facing street, there isn't too many places to drop and/or pick up game attendees, so there would be even less reason to use the space.)
Picture three just shows people going to and/or from a venue.
Picture four is rather humorous in that when a game was playing (the huge screen and hints of a full house being the key) spaces outside would be deserted, other than for late comers.
Picture 5 is extremely deceptive. In the plaza defined by 4 huge buildings multiple events are being undertaken, with fairly large well dispersed crowds in the space. Again, look at what the space actually is: streets and a walkway to and from sports arenas.
Perhaps they should provide free food....
Picture 6 just shows the general architecture of Farmer Stadium. A 21st Century football stadium is just a 21st Century football statium, used maybe 25 days per year.
Picture 7 shows what the space would look like most of the time.
