Closest public bear boxes would be the ones at the backpackers/Happy Isles trailhead parking lot. It's past this sign. Even if the sign says full, it's not updated regularly and is sometimes kept up to leave backpackers space (they're supposed to tell backpackers about the sign not always being accurate).

For the most part, bears aren't going to try and break into a car during the day, especially if there's plenty of human foot traffic. I stored a little bit of stuff in my car, but covered it.
At Grant Grove in Kings Canyon NP (where the bears also break into cars) I asked a park ranger about leaving my food in my car as I waited for my cabin to be ready. I was told I was OK since it was daylight and there were enough people walking around to discourage bears from breaking in. Of course breaking in is very different than a grab and flee, which bears have been known to do even where they don't break into cars.
Over there I saw plenty of bear boxes - even in day use areas. The parking lot at Crystal Cave had at least 6 bear boxes, as did the trailhead parking for Redwood Canyon. The latter may be used by backpackers, so I guess it made some sense.
