Not sure if this counts as "in the wild", but I usually get hundreds of street passes any time I go to an anime or video game convention. Tons of people playing 3DS while waiting in line or waiting for panels to start and stuff.
For more "real world" examples,
I usually get a handful every time I go to Disneyland.
I usually get one or two at the airport.
Employees at the mom and pop game shop I go to usually have their handhelds on hand if it's not busy.
I've been on two planes since the Switch came out. Both times, I was the only person playing a Switch.
